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. WebThe Unified thread angle is 60° and has flattened crests (Whitworth crests are rounded). From 1 ⁄ 4 in up to 1 + 1 ⁄ 2 in, thread pitch is the same in both systems except that the thread pitch for the 1 ⁄ 2 in bolt is 12 threads per inch (tpi) in BSW versus 13 tpi in the UNC.
