Tolerance Iso 2768 Mk Pdf Verified Jun 2026

ISO 2768-1 applies to dimensions of parts that are typically produced by metal removal or formed from sheet metal. It applies to dimensions like external sizes, internal sizes, step sizes, diameters, radii, distances, and chamfer heights.

It keeps technical drawings clean and legible.

General tolerances for linear and angular dimensions. Tolerance Iso 2768 Mk Pdf

| Tolerance Class | Tolerance Value | | :--- | :--- | | H | 0.1 mm | | | 0.2 mm | | L | 0.5 mm |

These tolerances dictate the allowable variation for angular features, measured in degrees and minutes. Length of the Shorter Side (mm) Tolerance Class m (Medium) Over 10 to 50 Over 50 to 120 Over 120 to 400 ISO 2768-2: Geometrical Tolerances (Class K) ISO 2768-1 applies to dimensions of parts that

If a specific feature on that same drawing requires a tighter fit (for instance, a bearing press-fit), the engineer will override the general tolerance by writing a specific tolerance directly next to that individual dimension (e.g.,

: Standardized baselines leave less room for interpretation or guesswork between the design office and the machine shop floor. General tolerances for linear and angular dimensions

| Nominal Length Range (mm) | Tolerance Class 'K' (mm) | | :--- | :--- | | up to 10 | 0.05 | | over 10 up to 30 | 0.1 | | over 30 up to 100 | 0.2 | | over 100 up to 300 | 0.4 | | over 300 up to 1000 | 0.6 | | over 1000 up to 3000 | 0.8 |

Usually relates to the longer side of the corner (e.g., 0.3mm to 0.8mm). Symmetry: Similar range to perpendicularity. Why Choose ISO 2768-mK?

| Nominal Size Range (mm) | Tolerance Class f (Fine) | Tolerance Class m (Medium) | Tolerance Class c (Coarse) | Tolerance Class v (Very Coarse) | | :--- | :--- | :--- | :--- | :--- | | 0.5 up to 3 | ±0.05 mm | ±0.1 mm | ±0.2 mm | – | | over 3 up to 6 | ±0.05 mm | ±0.1 mm | ±0.3 mm | ±0.5 mm | | over 6 up to 30 | ±0.1 mm | ±0.2 mm | ±0.5 mm | ±1.0 mm | | over 30 up to 120 | ±0.15 mm | ±0.3 mm | ±0.8 mm | ±1.5 mm | | over 120 up to 400 | ±0.2 mm | ±0.5 mm | ±1.2 mm | ±2.5 mm | | over 400 up to 1000 | ±0.3 mm | ±0.8 mm | ±2.0 mm | ±4.0 mm | | over 1000 up to 2000 | ±0.5 mm | ±1.2 mm | ±3.0 mm | ±6.0 mm |
