is the default tolerance class for linear dimensions. It is the most commonly used class for machined parts. iso 2768 medium tolerance

In mechanical engineering, the class is the global "gold standard" for general-purpose manufacturing. It provides a balanced set of permissible deviations that ensure functional accuracy while keeping production costs low by avoiding over-specification. What is ISO 2768 Medium Tolerance? It provides a balanced set of permissible deviations

Linear dimensions for external radii and chamfer heights (usually non-critical features) have a separate, slightly coarser table. | Nominal Dimension Range (Shorter leg length in

| Nominal Dimension Range (Shorter leg length in mm) | Tolerance Class (Fine) | Tolerance Class m (Medium) | Tolerance Class c (Coarse) | Tolerance Class v (Very Coarse) | | :--- | :--- | :--- | :--- | :--- | | Up to 10 | ± 1° | ± 1° | ± 1° 30' | ± 3° | | Over 10 up to 50 | ± 0° 30' | ± 0° 30' | ± 1° | ± 2° | | Over 50 up to 120 | ± 0° 20' | ± 0° 20' | ± 0° 30' | ± 1° | | Over 120 up to 400 | ± 0° 10' | ± 0° 10' | ± 0° 15' | ± 0° 30' | | Over 400 | ± 0° 5' | ± 0° 5' | ± 0° 10' | ± 0° 20' |

In the context of ISO 2768, medium tolerance refers to a specific level of tolerance class that provides a moderate level of precision for parts and components. This tolerance class is often used in general engineering and manufacturing applications where a moderate level of accuracy is required.
