Note: Breaking torque test applies to bolts and screws with thread less than M3 This uses the equations from ANSI B1 1-1974 and B18.3.1-1978 which calculates the area carrying the tensile load from the mean of the pitch diameter and the minor diameter. Multiply the failing force of the bolt (the maximum force the bolt can sustain before failure) by 4. S y. This shear strength must be greater than the amount of backwards thrust on the bolt generated by the cartridge being fired. Minimum breaking torques are valid for bolts and subjected to a tensile test. F – axial bolt force or load (N, lb) torque reduction due to lubrication (%) Note that standard dry torques are normally calculated to produce a tensile stress – or axial force or clamp load – in the bolt that equals to 70% of minimum tensile strength or 75% of proof strength. Bolt or Pin In Single Shear Equation and Calculator. St = 120,000 psi As = 0.3340 sq. So another number that must be calculated is bolt thrust. Tensile Strength. EICAC - Design ByFat Buddha Designs.
