Introduction
This standard specifies the manufacturing tolerances for cylindrical taps used in metric threads with grinding. It covers both coarse and fine pitch threads with tolerance classes ranging from 4H to 8H and 4G to 6G. The document provides detailed guidelines for ensuring precision and consistency in the production of these taps, which are essential tools in mechanical engineering.
