Fastener thread geometry
WebJan 4, 2024 · As a result, a screw thread offers a locking feature that would require a good amount of shear stress to break, making it great for fastening objects together. This kind of thread can be an external thread (like on a … WebThe stressed area in a bolt can be calculated as. A = (π / 4) (dn - 0.9743/ n)2 (1) where. A = stressed area (in2) dn = nominal bolt diameter (in) n = 1 / p = number of threads per inch. p = pitch, length per thread (in) Despite that a reduced area will reduce the breaking load of a bolt - coarse threads are used for clamping. Fine threads ...
