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)

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:
