The is more than just a file—it is a universal language between designers, machinists, and QC inspectors. Understanding the difference between the Medium class for linear tolerances and Class K for geometrical tolerances is essential to creating functional, cost-effective parts.
For sizes below 0.5 mm, indicate individual tolerance.

If you want to invoke ISO 2768-MK on your technical drawing, the general tolerance note should be placed in the title block or near the drawing notes. Use one of the following formats:
If you are a quality inspector and the drawing says “ISO 2768-MK,” here is your checklist: The is more than just a file—it is

In the world of technical drawing and mechanical engineering, specifying dimensions is only half the story. The other, often more critical, half is —the allowable limit of variation in a physical dimension. Without tolerances, mass production, interchangeable parts, and assembly would be impossible.
