While ISO 2768-mK is incredibly versatile, it is not a silver bullet. You should bypass general tolerances in the following scenarios:
Therefore, when you see in a drawing title block, it means the component must be manufactured to Medium linear tolerances and Medium geometric tolerances . ISO 2768-m (Part 1): Linear and Angular Dimensions
| Nominal Length of Shorter Side (mm) | Permissible Deviation (mm/m or degrees) | | :--- | :--- | | Up to 10 | ±1° | | >10 up to 50 | ±0°30' | | >50 up to 120 | ±0°20' | | >120 up to 400 | ±0°10' | | >400 | ±0°5' |
By using "mk", a manufacturer instantly knows that the component requires standard, medium-precision machining. This is typically achievable via conventional milling, turning, and drilling operations without requiring expensive secondary finishing processes like grinding or honing. Part 1: Linear Dimensions (The "m" Class)
These tolerances apply to features like external lengths, step heights, and diameters.
