The document specifies deviations for pitch and crest diameters for ISO general purpose metric screw threads (M) conforming to ISO 261. The tolerance system refers to the basic profile according to ISO 68-1. The deviations specified are derived from the fundamental deviations and tolerances specified in ISO 965-1.
