WebProof load is defined as the maximum tensile force that can be applied to a bolt that will not result in plastic deformation. A material must remain in its elastic region when loaded up to its proof load typically between 85-95% … WebLoad Est. Shear Strength Minimum Tensile Strength Minimum Yield Strength The torque values can only be achieved if nut (or tapped hole) has a proof load greater than or equal to the bolt's minimum ultimate tensile strength. Clamp load calculated as 75% of the yield strength for the B7 specified in ASTM A193. WebProof load is the limit of the elastic range of the bolt. Designing for the use of bolts according to proof load can help prevent plastic deformation. As long as a bolt is never tensioned beyond its specified proof load, you can … dutch diamonds strain
