WebbSt: bolt tensile strength. As: tensile stress area. The value for tensile stress area can be determined from: As = π/4 x (D - (.938194 x p))². Where: D: bolt diameter. p: 1/threads per inch (TPI) Clamp load is typically around 75% of a bolt’s proof load; that is, the highest stress the bolt can accommodate before experiencing plastic ... Webb31 maj 2012 · From SAE J429: the stress area of 10-32 is 0.0200 sq. inch. multplied by 150000 PSI minimum tensile stress for gr 8 = 3000 lbs minimum tensile load. The fastener must meet or exceed this load when taken to total break. The proof load stress is 120000 PSI for gr 8, multplied by 0.0200 = 2400 lbs.
