However, the sizes stay consistent with standard screws, studs, and bolts. Generally, tap sizes start from zero and can go up to 14. The diameter of the size zero tap measures around .0600. When the tap number increases, the diameter of the taps also increase by .0130.

There are three different classes.(1A,2A,3A, 1B,2B,3B). These all are the mensuration of looseness or tightness of the thread fit. As the number increases, as does the tightness of the fit.
