: The governing international standard for general engineering tolerances. The is defined in Annex A of ISO

These values apply per 100 mm of length. For longer lengths, the tolerance is prorated but limited by the maximum deviation. The instructs that tolerances for external radii and

The instructs that tolerances for external radii and chamfer heights follow the same "M" class limits as linear dimensions, but applied to the radius or chamfer size.

A shaft length of 75 mm without an individual tolerance → allowed length = 74.7 to 75.3 mm.

The designation dictates strict geometric rules to ensure components fit together. Breakdown of ISO 2768-mk-e The string is divided into four distinct components:
