The Bolted Joint Analysis calculator allows for stress analysis of a bolted joint, accounting for preload, applied axial load, and applied shear load. No lubrication. This shear strength must be greater than the amount of backwards thrust on the bolt generated by the cartridge being fired. - ISO 898 applies to bolts, screws and studs with coarse pitch thread M1.6 to M39 and fine pitch thread M8 X 1 to M39 X 3 with triangular ISO thread, - It does not apply to set screws and similar threaded fasteners. Tensile stress, also known as tension is the state of stress causing expansion. Thread Tensile Stress Area Calculator. Fp – Pre load. One of the problems in predicting thread stripping strength is that, without considering such effects as thread bending, nut dilation or bellmouthing, an optimistic result occurs. Note: Bolt strength as calculated in Threads is a close approximation for the strength of the shaft of the bolt. Tensile strength of bolts. Print this page .
