ForUnified inch screw threads there are 3 thread classes for external threads – 1A, 2A and 3A, and 3 for internal threads – 1B, 2B and 3B. All are clearance fits, which means they assemble without interference. The higher the class number, the tighter the fit. The designatore ‘A’ denotes an external thread, ‘B’ denotes an internal Overwire measurements. 1 3/8 - 12 UNFPossible Thread Classes. External Threads. 2A, 3A.
