Classes of threads are differentiated by the amount of tolerance and allowance specified. Indicating gaging is typically mastered at maximum material condition. This is the minimum Pitch diameter tolerance limit for I.D. threads and the maximum Pitch diameters tolerance limit for O.D. threads. BASIC SIZE THREAD CLASS TOLERANCE OVERLAP THREAD ...

The Thread Disk™ engineering software (TDWin™ ) calculates critical dimensions for threads based on ANSI tables and formulas. Thread types supported by the program include: UN, UNJ and UNR Series, Acme, Stub Acme, Stub Acme Modified I and II, Metric M & MJ, 7° X 45° Buttress, and General Purpose Pipe Threads.
All thread dimensions, internal & external are based on this dimension. MINOR DIAMETER - ROOT: Must clear the mating product's minor diameter.
