WebThe bolt grades are numbered according to the tensile strengths, with decimals used for variations at the same strength level. Bolts and screws are available in all grades listed. Studs are available in grades 1, 2, 4, 5, 8, and 8.1. (A stud is a metal rod or shaft featuring threads on both sides) ASTM specifications are listed in Table 8–10. WebSep 12, 2024 · Calculation for bolt shear strength For the shear strength, you can approximate the shear yield stress to 0.5 of the tensile yield stress (this is a very conservative approximation if you compare it to tables from Eurocode). So the shear load should be in the order of (at least) 150 kg.

WebCoarse pitch threads are preferred and should be used whenever possible, as stated in ASME B1.13M.
