Metric Bolt Strength Chart Proof load. proof 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% of the yield strength. acceptable clamp load is typically 75% of proof load. The metric thread standard iso 965 2 provides the limits only for classes 6h & 6g*. in all other cases, calculations must be made manually according to the below formulas or by our threading calculator. * for threads over 1.4 mm and classes 5h & 6h for threads up to and including 1.4 mm.
Bolt Tensile Strength Chart Find the design properties for metric hexagonal bolts m5 to m39, such as stress area, yield strength, ultimate tensile strength, shear resistance, bearing resistance, and punching resistance. the table shows the values for different bolt classes, hole diameters, and steel grades according to en 1993 1 8.
