Onceyou know your wire diameter, you need to find out what is the premissable Measurement for your pitch diameter (Depending on the class).

Asthe basic/nominal thread size increases, the class tolerance increases, example the tolerance for a 1/4-20 UNC -2B is 0.0049, and for a 3/8-16 UNC-2B is 0.0057. Also, the finer the threads, for the same basic/nominal thread size, the class tolerances decrease, example the tolerance for a 1/4-20 UNC-2B is 0.0049, and for a 1/4-28 UNF
