WebThe most common thread types that have a multi-start thread are the trapezoidal thread (Tr) and the saw thread (S). In addition to the diameter and the pitch, the identification or designation also indicates the pitch in P or the number of threads. For example: WebThere are 6 types of class fit for unified threads: Classes 1A and 1B - Loosest tolerance, it’s very rare. Usually used when quick assembly/disassembly is required. Classes 2A and 2B - “Medium” tolerance, it’s the most common fit. This is the best option to balance thread performance and convenience.
