Iso 2768-mh Tolerance Chart Jun 2026

Engineers spend less time specifying tolerances on every feature.

| Class | Linear Tolerance | Geometrical Tolerance | Typical Application | |-------|----------------|------------------------|----------------------| | f (fine) | Tight | Tight | Precision machining, close fits | | | Medium | Varies (H) | General workshop practice | | c (coarse) | Loose | Loose | Rough cuts, welded assemblies | | v (very coarse) | Very loose | Very loose | Castings, large fabrications | iso 2768-mh tolerance chart

These tolerances apply to external/internal sizes, diameters, and distances. Nominal Length Range (mm) Tolerance (± mm) 3 to 6 6 to 30 30 to 120 120 to 400 400 to 1000 1000 to 2000 2000 to 4000 Geometric Tolerances (H - High) Engineers spend less time specifying tolerances on every

| Nominal Dimension Range (mm) | Tolerance for engineers working with precision parts

This is where the ISO 2768 standard comes into play. Specifically, for engineers working with precision parts, the designation is one of the most common and critical specifications to understand.

Runout tolerance = for all nominal sizes (independent of diameter).
