Iso 2768-mh Tolerance Chart ((free)) Jun 2026

This defines the tolerances for linear and angular dimensions (length, radii, diameters). The "m" stands for Medium .

(very coarse). The "m" class offers a practical balance of precision and manufacturability for standard machined components. 2. The Second Letter: "H" (Higher Geometric Tolerance)

If a feature is critical for a "press-fit" (like a bearing housing) or requires extreme precision for airtight seals, . In those specific cases, you must manually define a tighter tolerance (e.g., +/- 0.01mm) directly on that dimension.

The power of the standard lies in its tabulated data. Below is the essential content of the ISO 2768-mh chart.
