Introduction

In the intricate world of industrial procurement, maintenance, repair, and operations (MRO), and design engineering, the smallest components often carry the greatest weight. A seemingly minor detail, such as the precise diameter of a wood screw, can significantly impact project integrity, material compatibility, and overall structural performance. Imagine a meticulously planned assembly brought to a halt, or worse, compromised in the field, simply because a fastener's dimensions were misunderstood or inaccurately sourced. This isn't just a hypothetical scenario; it's a common pain point for procurement managers striving for efficiency, MRO buyers battling downtime, and design engineers pushing the boundaries of innovation.

Understanding the exact specifications of fasteners is not merely about technical adherence; it's about mitigating risk, ensuring longevity, and optimizing the Total Cost of Ownership (TCO) for every project. This post will delve into one such critical specification: the diameter of a number 6 wood screw. We will explore what "number 6" truly signifies within the U.S. gauge system, its precise dimensions, and why this seemingly simple measurement holds profound implications for material selection, application, and overall project success. Furthermore, we will discuss how leveraging a platform dedicated to verified, U.S.-made industrial components can transform your procurement process, ensuring accuracy, resilience, and strategic advantage.

The Anatomy of a Wood Screw: Beyond the Basics

Before we focus on the specific dimensions of a number 6 wood screw, it's essential to understand the fundamental components that define any screw and how each contributes to its overall function and performance. A screw is far more than just a threaded shaft; it's a precisely engineered device designed to create a secure, removable joint.

Understanding Screw Design: Head, Shank, Thread, Point

Every screw comprises several key elements, each with a distinct role:

Head: This is the top part of the screw, designed to be engaged by a driving tool (e.g., screwdriver, wrench) and to bear against the surface of the material being fastened. Head types vary widely, from flat and round to oval and pan, each suited for different aesthetic and functional requirements.
Drive Style: Integral to the head, the drive style dictates the type of tool required for insertion and removal. Common types include slotted, Phillips, square (Robertson), Torx, and hex. The choice of drive style impacts torque transfer, cam-out resistance, and ease of installation.
Shank (Unthreaded Portion): Not all screws have an unthreaded shank, but for those that do, this smooth section helps pull materials together tightly without the threads interfering with the top piece. In wood screws, the shank diameter is usually larger than the thread's root diameter and smaller than its major diameter.
Thread: The helical ridge that wraps around the screw's body. The threads are designed to cut into or engage with the material, providing the holding power. Key thread parameters include pitch (distance between threads), lead (distance the screw advances in one revolution), and thread angle.
Major Diameter: This is the largest diameter of the screw, measured from the crest of the thread on one side to the crest on the opposite side. When people refer to the "diameter" of a screw, they are typically referring to the major diameter.
Minor Diameter (Root Diameter): This is the smallest diameter of the screw, measured at the base or root of the threads. It is critical for determining the screw's shear strength.
Point: The tapered end of the screw, designed to help initiate penetration into the material. Points can be sharp (type A), blunt, or self-drilling, depending on the application.

Each of these elements is precisely engineered, and variations in any one of them can significantly alter the screw's suitability for a particular application. For procurement managers, MRO buyers, and design engineers, a thorough understanding of these components is foundational to selecting the correct fastener, ensuring optimal performance, and preventing costly errors.

Why Diameter Matters: Strength, Fit, and Application

The diameter of a wood screw is arguably its most critical dimension after its length. Its importance stems from several key factors:

Holding Power and Shear Strength: A larger diameter generally means more material in the screw's core (minor diameter) and more thread engagement with the surrounding material. This translates directly to increased shear strength (resistance to forces parallel to the screw's axis) and pull-out resistance (resistance to forces perpendicular to the screw's axis). Selecting a screw with insufficient diameter can lead to premature failure under load.
Material Compatibility and Pilot Hole Sizing: The screw's diameter dictates the size of the pilot hole required. An incorrectly sized pilot hole—too small or too large—can lead to issues. A pilot hole that is too small can cause the wood to split, especially in hardwoods, or make the screw difficult to drive, potentially stripping the head or breaking the screw. A pilot hole that is too large reduces the thread's engagement, diminishing holding power. The diameter ensures a perfect fit, allowing the threads to properly bite into the material without causing damage.
Application-Specific Requirements: Different applications demand different screw diameters. Delicate woodworking might require smaller diameters to avoid splitting, while heavy construction might necessitate larger diameters for maximum load-bearing capacity. The aesthetic impact of the screw head, which scales with diameter, is also a consideration in visible applications.
Tooling and Installation: The diameter also influences the type and size of driving tool needed, as well as the torque required for successful installation. Proper diameter ensures compatibility with standard bits and drivers, preventing cam-out and ensuring efficient assembly.

For those overseeing complex projects, understanding the nuanced role of screw diameter extends beyond basic selection; it becomes a strategic imperative. It's about optimizing performance, ensuring compliance, and ultimately safeguarding the integrity of the finished product.

The American System: Gauges vs. Imperial/Metric

Unlike the straightforward measurement systems used for length (e.g., inches or millimeters), screw diameters in the U.S. often follow a numerical gauge system for smaller fasteners. This system can sometimes be a source of confusion for those accustomed to direct measurement.

The Gauge System: For screws smaller than 1/4 inch, the diameter is typically referred to by a "number" ranging from #0 to #24. This number is not a direct measurement in inches or millimeters but rather an arbitrary gauge size that corresponds to a specific major diameter. The higher the number, the larger the screw's diameter. This system originated from old wire gauge standards and became a convention in fastener manufacturing.
Imperial Measurements: For screws 1/4 inch and larger, the diameter is usually expressed directly in fractional inches (e.g., 1/4", 5/16", 3/8"). This offers a more intuitive understanding of the physical size.
Metric System: In countries that primarily use the metric system, screw diameters are always expressed in millimeters (e.g., M3, M4, M5), directly indicating the major diameter. While U.S. manufacturing primarily adheres to the imperial gauge system, understanding metric equivalents is increasingly important in a globally interconnected supply chain. However, at Maden.co, our unwavering focus is on American manufacturing, ensuring consistency and adherence to U.S. industry standards.

Navigating these different measurement systems requires precision and a clear understanding of conversion where necessary, though for U.S.-made components, the gauge system remains predominant for smaller diameters. Our platform at Maden.co is designed to provide clear, consistent specifications, allowing buyers to confidently source U.S.-made products with accurate dimensions.

Decoding Number 6 Wood Screw Diameter

Now that we've established the foundational knowledge of screw anatomy and measurement systems, let's zoom in on our specific target: the number 6 wood screw. Understanding this particular size is critical for countless applications across diverse industries.

What "Number 6" Actually Means (Gauge System Explanation)

As discussed, the "number 6" in a #6 wood screw refers to its gauge size within the standardized system for fasteners in the United States. It's important to reiterate that this is not a direct measurement in inches. Instead, it's an index number that corresponds to a specific major diameter.

The relationship between gauge number and diameter follows a formula, but for practical purposes, it's easier to reference charts. For gauge sizes from #0 to #10, the diameter increases by approximately 0.013 inches for each increment in the gauge number.

A #0 screw has a major diameter of approximately 0.060 inches.
For every subsequent number, you add 0.013 inches.
So, for a #6 screw: 0.060 + (6 * 0.013) = 0.060 + 0.078 = 0.138 inches.

This mathematical relationship ensures consistency across manufacturers adhering to U.S. standards. However, slight variations due to manufacturing tolerances should always be expected.

The Precise Diameter (Major Diameter, Thread Diameter)

The major diameter of a number 6 wood screw is consistently around 0.138 inches (or approximately 3.51 mm). This is the measurement across the widest part of the threads.

It's crucial to distinguish this from the minor diameter (root diameter), which for a #6 wood screw, is typically in the range of 0.090 to 0.100 inches (2.29 to 2.54 mm), depending on the thread profile and manufacturer. The minor diameter is relevant for determining the pilot hole size in the piece being fastened and for calculating the screw's shear strength.

For design engineers, especially, knowing both the major and minor diameters is critical for:

Accurate Hole Sizing: Selecting the correct drill bit for pilot holes to ensure proper thread engagement without splitting the material.
Stress Analysis: Calculating the load-bearing capacity and potential failure points of an assembly.
Component Fit: Ensuring that the screw will pass through clearance holes in mating components.

Comparing to Other Common Gauges (e.g., #4, #8, #10)

To put the #6 wood screw's diameter into context, let's briefly compare it to other commonly used gauges:

#4 Wood Screw: Major diameter of approximately 0.112 inches (2.84 mm). A finer, less robust screw, often used for delicate applications or thin materials.
#6 Wood Screw: Major diameter of approximately 0.138 inches (3.51 mm). A versatile, mid-range size suitable for a broad array of general-purpose applications, balancing holding power with reduced risk of material splitting.
#8 Wood Screw: Major diameter of approximately 0.164 inches (4.17 mm). A common choice for general construction, furniture, and cabinetry where more substantial holding power is required.
#10 Wood Screw: Major diameter of approximately 0.190 inches (4.83 mm). A robust fastener used for heavier-duty applications, larger assemblies, and where maximum pull-out resistance is needed.

This comparison highlights why the #6 wood screw is so frequently specified. It offers a robust solution for many applications without being excessively large, making it a staple in numerous industrial and commercial settings.

Variations and Tolerances in Manufacturing

While standards provide a nominal diameter, it's important for procurement professionals and design engineers to understand that real-world manufacturing always involves tolerances. These are acceptable deviations from the nominal size. For U.S.-made fasteners, these tolerances are typically very tight, ensuring high levels of consistency.

Material Specifics: The type of material (e.g., brass, steel, silicon bronze) can sometimes influence the precise manufacturing process, leading to minute, but acceptable, variations within specified tolerances.
Thread Type: Different thread forms (e.g., coarse, fine) can also subtly affect the effective major and minor diameters within the allowed tolerance range.
Industry Standards: Adherence to established industry standards, such as those by ASME (American Society of Mechanical Engineers) or ANSI (American National Standards Institute), dictates these tolerance ranges. When sourcing through Maden.co, you can be confident that our verified U.S. manufacturers produce components that meet or exceed these critical standards, offering predictable performance and ensuring compliance with specifications like DIN or NPT where applicable. This commitment to industrial excellence and supply chain transparency is a core value we uphold.

For a design engineer meticulously crafting a new marine application, the selection of a fastener with precise dimensions and superior corrosion resistance is non-negotiable. A slight deviation in diameter, or a material unable to withstand harsh saltwater environments, could compromise the entire assembly. This is where understanding the exact specifications, like the diameter of a number 6 wood screw, and choosing materials like silicon bronze becomes paramount. Consider, for instance, the critical role of an oval slot drive silicon bronze wood screw in securing vital components on a boat; its specific gauge and material ensure both structural integrity and longevity in demanding conditions.

Material Science and Wood Screw Performance

The performance of a wood screw extends far beyond its dimensions; the material from which it is manufactured plays an equally critical role. Different materials offer unique properties in terms of strength, corrosion resistance, aesthetics, and cost, directly influencing the suitability of a #6 wood screw for a given application.

Brass Wood Screws: Properties, Applications, Aesthetic Value

Brass is an alloy primarily composed of copper and zinc, known for its distinctive golden hue and several desirable properties, making it a popular choice for specific #6 wood screw applications.

Properties:
- Corrosion Resistance: Brass exhibits good resistance to corrosion, particularly from water and certain chemicals, though it can tarnish over time, forming a protective patina.
- Workability: It is relatively soft and easy to machine, which contributes to its consistent manufacturing.
- Conductivity: Brass is electrically conductive, a property that can be relevant in certain specialized applications, though less so for general fastening.
- Aesthetics: Its appealing golden color and ability to polish to a high luster make it highly valued in visible applications.
Applications:
- Fine Woodworking and Furniture: Often chosen for high-end furniture, cabinetry, and decorative fixtures where the screw head will be visible and contribute to the overall aesthetic. The material's softer nature also makes it less likely to scratch delicate wood finishes.
- Marine Environments (Limited): While more resistant than steel, brass is not as corrosion-resistant as silicon bronze in harsh saltwater conditions but can be used in less demanding marine interior applications.
- Hardware and Hinges: Frequently used to attach brass hardware, hinges, and escutcheons, ensuring material compatibility and a consistent appearance.
Aesthetic Value: The ability of brass to age gracefully, developing a rich, darker patina over time, is a significant draw for designers and craftsmen seeking a classic or antique look. For precision and aesthetic appeal in your projects, a high-quality round slot drive brass wood screw provides both reliable fastening and a touch of timeless elegance.

Silicon Bronze Wood Screws: Corrosion Resistance, Marine Use, Durability

Silicon bronze is a superior alloy in many demanding environments, particularly where corrosion resistance is paramount. It is an alloy of copper with silicon as the primary alloying agent, often with smaller amounts of manganese, zinc, and iron.

Properties:
- Exceptional Corrosion Resistance: Silicon bronze offers outstanding resistance to saltwater, acids, alkalis, and atmospheric corrosion, surpassing stainless steel in certain chemical environments.
- High Strength: It possesses good tensile strength and ductility, making it a robust fastener capable of handling significant loads without brittleness.
- Durability: Its inherent resistance to degradation ensures long-term performance and reduced maintenance, leading to a lower TCO over the product lifecycle.
- Non-Magnetic: A key characteristic for specialized applications where magnetic interference must be avoided.
Applications:
- Marine Construction and Shipbuilding: The material of choice for fastening wood components on boats, docks, and other structures exposed to saltwater. This includes securing planks, trim, and hardware on vessels.
- Outdoor Architectural Elements: Used in high-end exterior construction, especially near coastal areas, for decks, pergolas, and decorative elements where longevity and resistance to weathering are essential.
- Historical Restoration: Its superior lifespan and aesthetic similarity to traditional bronze make it ideal for the restoration of historic buildings and artifacts.
- Chemical Processing Equipment: Employed in environments where exposure to corrosive chemicals necessitates a highly resistant fastener.

For critical applications requiring maximum longevity and resistance to the harshest elements, the robust performance of a silicon bronze wood screw, such as an oval slot drive silicon bronze wood screw, is unmatched. Its superior properties make it an indispensable choice for design engineers focused on durability in demanding conditions.

Other Common Materials: Steel, Stainless Steel

While brass and silicon bronze offer specialized advantages, other materials are widely used for #6 wood screws:

Steel: Plain steel screws are common for general-purpose indoor applications where corrosion is not a concern. They are strong and economical but will rust if exposed to moisture without a protective coating (e.g., zinc plating).
Stainless Steel: Alloys like 304 and 316 stainless steel offer good corrosion resistance (especially 316 in marine environments, though silicon bronze often outperforms it in specific saltwater immersion scenarios) and high strength. They are more expensive than plain steel but provide a significant upgrade in durability and resistance to rust.

The Importance of Material Certification for Industrial Use

For procurement managers and MRO buyers, merely specifying a material is often not enough. In industrial applications, material certification is paramount. This documentation verifies that the fastener material meets specific chemical composition, mechanical property, and manufacturing standards.

Quality Assurance: Certifications provide confidence that the material will perform as expected under specified conditions.
Compliance: Many industries (e.g., aerospace, marine, medical, construction) have stringent regulatory requirements that mandate certified materials.
Traceability: Certification ensures traceability from raw material to finished product, vital for quality control and auditing.

Head Types and Drive Styles: Practical Implications for Procurement

Beyond diameter and material, the head type and drive style of a #6 wood screw are crucial considerations for procurement managers, MRO buyers, and design engineers. These features directly impact ease of installation, final appearance, torque application, and overall suitability for a specific project.

Slotted Drives: Tradition and Torque Considerations

The slotted drive is one of the oldest and most traditional drive styles. It features a single slot cut across the head of the screw, designed to engage with a flat-blade screwdriver.

Tradition and Aesthetics: Slotted screws are often preferred in historical restorations or traditional woodworking where authenticity is desired. Their classic appearance can complement period-specific designs.
Tool Availability: Flat-blade screwdrivers are ubiquitous, making slotted screws accessible even in rudimentary toolkits.
Torque Considerations: A significant drawback of slotted drives is their tendency to "cam-out" – the screwdriver slipping out of the slot – especially when applying high torque. This can damage the screw head, the screwdriver, or the surrounding material. For this reason, they are less ideal for applications requiring very high torque or repeated removal and insertion.
Manufacturing Simplicity: The slot is relatively simple to machine, which can sometimes contribute to their cost-effectiveness.

For a classic look combined with the reliable fastening power of brass, a flat slot drive brass wood screw in a #6 diameter is an excellent choice for visible applications in fine cabinetry or furniture where moderate torque is sufficient.

Phillips, Square, Torx: Modern Alternatives and Benefits

Modern drive styles have evolved to address the limitations of the slotted drive, offering improved torque transfer and cam-out resistance.

Phillips Drive: Invented by Henry F. Phillips, this drive has a cross-shaped recess that provides four contact points. It offers better cam-out resistance than a slot drive but is still designed to cam-out at a certain torque to prevent overtightening and stripping. It is one of the most common drive types globally.
Square (Robertson) Drive: Developed by P.L. Robertson, this drive features a square recess. It is renowned for its excellent cam-out resistance, allowing for high torque application without slippage. Square drive screws are particularly popular in woodworking and construction due to their ease of use, even with one hand.
Torx (Star) Drive: Also known as a star drive, the Torx drive has a 6-point star-shaped recess. It offers superior torque transfer and virtually eliminates cam-out. Torx drives are widely used in automotive, electronics, and construction industries where precise torque control and high reliability are critical.
PoziDriv: An improved version of the Phillips drive, with additional smaller slots between the main cross recesses, offering even better grip and cam-out resistance than a standard Phillips.

The selection of a drive style has direct implications for installation efficiency and fastener integrity. For MRO buyers, standardizing on a particular drive type can simplify tool inventories, while for design engineers, choosing a high-torque drive can ensure robust assemblies.

Head Styles: Flat, Round, Oval, Pan - When to Choose Which

The head style of a #6 wood screw dictates how it sits on or in the material, affecting both appearance and functional load distribution.

Flat Head (Countersunk): Designed to sit flush with or slightly below the surface of the material when countersunk. This creates a smooth, snag-free finish, ideal for applications where aesthetics and a flush surface are important (e.g., furniture, flooring, hinges).
Round Head: Sits entirely above the surface of the material, providing a decorative, domed appearance. The larger bearing surface under the head can offer better clamping force on softer materials, and it's easier to remove without damaging the surrounding material. Often used in traditional joinery or where a distinctive look is desired. (Such as the round slot drive brass wood screw referenced earlier).
Oval Head (Raised Countersunk): A hybrid of flat and round heads. The underside is tapered to allow countersinking, while the top has a rounded, decorative dome that sits slightly above the surface. This offers a finished look while still allowing for a relatively smooth surface. It's common in architectural hardware and decorative trim. (As seen in the oval slot drive silicon bronze wood screw).
Pan Head: Features a slightly rounded, low-profile dome with a flat bearing surface underneath. It sits above the material but has a wider, flatter profile than a round head. Pan heads provide good clamping force and a clean, unobtrusive appearance, often used in sheet metal, plastic, or general assembly where a flush finish isn't critical but a strong hold is.

Understanding these distinctions allows procurement managers to specify the exact screw needed for both functional performance and the desired finished aesthetic, preventing costly reworks and ensuring project success.

Selecting the Right Number 6 Wood Screw for Your Project

Choosing the correct #6 wood screw involves more than just knowing its diameter and material. It requires a holistic approach that considers the specific application, proper installation techniques, and overall project requirements.

Application-Specific Considerations: Furniture, Cabinetry, Marine, General Construction

The versatility of the #6 wood screw means it finds its place in a wide array of applications. However, optimal selection requires matching the screw's characteristics to the demands of the environment and function.

Furniture and Cabinetry: Here, aesthetics, material compatibility, and resistance to pull-out are crucial. Brass screws (like a round slot drive brass wood screw) or zinc-plated steel screws are common. Flat or oval heads are often preferred for a flush or decorative finish. The #6 diameter provides sufficient holding power for many joints without being overly bulky or prone to splitting thinner stock.
Marine Applications: As highlighted, saltwater environments demand exceptional corrosion resistance. Silicon bronze (e.g., an oval slot drive silicon bronze wood screw) is often the superior choice, even over stainless steel in some contexts, to prevent galvanic corrosion and ensure long-term structural integrity. Drive style and head type might prioritize durability and ease of maintenance in harsh conditions.
General Construction: For interior framing, subflooring, or general fastening where appearance is less critical but strength is key, standard steel or galvanized #6 screws are often used. Phillips or square drives are favored for their efficient torque transfer.
Outdoor Structures (Non-Marine): Pressure-treated lumber requires screws with appropriate corrosion resistance to prevent premature failure, as the chemicals can accelerate corrosion of unprotected fasteners. Coated screws or stainless steel are typically recommended.

For a procurement manager under pressure to source a specific, compliant fastener, or a design engineer needing material certifications for a new prototype, the ability to quickly find and verify a U.S.-made part tailored to these specific application needs is a game-changer.

Pilot Hole Best Practices for #6 Screws (Softwood, Hardwood, Composites)

The pilot hole is critical for successful screw installation, especially for wood screws, preventing material splitting and ensuring optimal thread engagement. The diameter of the pilot hole depends on the screw's minor diameter and the density of the material.

Softwoods (e.g., Pine, Cedar): For softwoods, the pilot hole should generally be slightly smaller than the minor diameter of the screw to ensure maximum thread engagement. For a #6 wood screw, a pilot hole around 5/64" or 3/32" is often suitable, though testing on scrap material is always recommended.
Hardwoods (e.g., Oak, Maple, Cherry): Hardwoods are denser and more prone to splitting. The pilot hole should be closer to the screw's minor diameter, or sometimes even slightly larger, to ease insertion and prevent damage. For a #6 wood screw in hardwood, a pilot hole of 7/64" is a common starting point.
Composites and Engineered Wood: These materials can vary greatly in density and composition. Always refer to the manufacturer's recommendations for pilot hole sizing. In general, a pilot hole slightly larger than the screw's minor diameter can be a safe bet to prevent delamination or cracking.
Clearance Hole: When joining two pieces where only the bottom piece needs to be threaded, a clearance hole is drilled through the top piece. This hole should be equal to or slightly larger than the screw's major diameter (0.138" for a #6) to allow the screw to pass freely, letting the screw head pull the pieces tightly together.

Fastener Length: Balancing Penetration and Pull-Out Strength

While our focus is on diameter, the length of a #6 wood screw is equally vital for ensuring adequate holding power.

General Rule of Thumb: For optimal pull-out resistance, the screw should penetrate the base material by at least two-thirds of its total length, or ideally, have threads engaged in the base material for at least the thickness of the top piece being fastened.
Material Thickness: The screw's length must be appropriate for the combined thickness of the materials being joined, ensuring it doesn't protrude undesirably or, conversely, is too short to provide sufficient purchase.
Shear vs. Pull-Out: While diameter contributes to shear strength, length is primarily critical for pull-out resistance. A longer screw provides more surface area for the threads to grip the material.

Tooling and Installation: Ensuring Proper Fit and Preventing Damage

Proper tooling and installation techniques are essential to fully leverage the specified properties of a #6 wood screw.

Correct Driver Bit: Using the correct size and type of driver bit (e.g., flat, Phillips, square, Torx) for the screw's drive style is crucial to prevent cam-out, stripping of the head, and damage to the material.
Drill Speed and Torque: When using power tools, selecting the appropriate drill speed and torque setting prevents overtightening, stripping threads in the wood, or snapping the screw.
Countersinking: For flat or oval head screws, proper countersinking creates a clean, flush finish. This requires using a countersink bit that matches the angle of the screw head.

By adhering to these best practices, procurement managers can specify not only the right #6 wood screw but also ensure that installation crews have the knowledge and tools to maximize its performance, enhancing project quality and longevity.

FAQ

Q1: What does "number 6" actually mean for a wood screw diameter?

A1: The "number 6" refers to a standardized gauge size in the American fastener system, not a direct measurement in inches. It corresponds to a major diameter of approximately 0.138 inches (or about 3.51 mm). This gauge system is used for smaller screws, with the number increasing as the diameter gets larger.

Q2: Why is the precise diameter of a #6 wood screw so important for industrial applications?

A2: The precise diameter is crucial for several reasons: it dictates the screw's holding power and shear strength, ensures proper fit with pilot holes to prevent wood splitting or loose connections, and is essential for meeting specific engineering and compliance standards. An incorrect diameter can lead to structural failure, costly rework, and project delays.

Q3: What materials are common for #6 wood screws, and how do they differ in performance?

A3: Common materials include brass, silicon bronze, steel, and stainless steel. Brass offers good corrosion resistance and aesthetic appeal for visible applications. Silicon bronze provides exceptional corrosion resistance, especially in harsh marine environments, and high durability. Steel is strong and economical for general-purpose use but needs plating for corrosion protection, while stainless steel offers good strength and improved corrosion resistance over plain steel.

Q4: How does Maden.co help procurement managers find the right #6 wood screws and other U.S.-made components?
