Iso 2768-mh Tolerance Chart ~upd~ Jun 2026

The following tolerances apply to linear dimensions such as external sizes, internal sizes, step sizes, diameters, and radii. Nominal Size Range (mm) Tolerance (± mm) Over 3 to 6 Over 6 to 30 Over 30 to 120 Over 120 to 400 Over 400 to 1000 Over 1000 to 2000 Over 2000 to 4000 2. External Radii and Chamfer Heights

Based on the length of the shorter side. For sides up to 100mm, class h allows 0.2mm variance . iso 2768-mh tolerance chart

While primarily for material removal (like CNC machining), it can be applied to other processes with special examination. ISO 2768-2 The following tolerances apply to linear dimensions such

Thus, the notation "ISO 2768-mh" instructs the manufacturer to apply the class from Part 1 for linear/angular dimensions, and the 'h' (fine) class from Part 2 for geometrical tolerances. For sides up to 100mm, class h allows 0
