If you see a drawing note stating "General tolerances ISO 2768-mk" , the manufacturer must follow specific tolerance classes without cluttering the drawing with individual ± values for every hole, slot, or edge. The notation ISO 2768-mk combines two distinct tolerance classes from two parts of the standard: iso 2768-mk pdf

What is ISO 2768? ISO 2768 is an international standard created for general tolerances . It applies to linear dimensions, angular dimensions, radii, chamfers, and flatness/straightness that are not individually tolerance-indicated on a technical drawing. | Nominal Size Range (mm) | Tolerance (mm)

| Nominal Size Range (mm) | Tolerance (mm) | | :--- | :--- | | 0.5 up to 3 | ±0.2 | | >3 up to 6 | ±0.5 | | >6 up to 30 | ±1.0 | | >30 up to 120 | ±2.0 | Class k (sometimes called "K" or standard precision for geometry) applies to features that are not individually toleranced. Values are based on the nominal length of the feature . It applies to linear dimensions, angular dimensions, radii,
