Product Specifications
General Information 0
Strainsert fasteners utilize an exclusive internal gaging method (U.S. Patent #2;,873,341) to indicate bolt tension due to preload and subsequent service loads with strain gage accuracy. They are the first fasteners to provide a means for accurate, independent inspection of an assembled bolt for preload, thereby enhancing the structural integrity and reliability of both the bolt and the assembly. Feature Measurement of preload induced in fasteners Accurate tightening of fasteners within 1% of induced load Uniform tightening of fasteners in a bolt pattern
