Part 1 specifies four tolerance classes. The designer selects one based on the functional requirements of the part. Review: ISO 2768 General Tolerances PDF – The
ISO 2768-m. Never just "m".By using these general tolerances, manufacturers can avoid unnecessary costs. If a shop can meet the general tolerance class using standard equipment, they do not need to slow down production to achieve unnecessary precision on non-critical features. Correction: Always write the full callout: ISO 2768-m
For radii (R) and chamfer heights (h), the tolerances are slightly different:
