General Tolerance Iso 2768-mk Link Jun 2026

Applies to flatness, straightness, perpendicularity, symmetry, and circular runout.

Cost. Tight tolerances require slower machining speeds, specialized tooling, and 100% inspection. 'mk' provides sufficient accuracy for 80% of mechanical parts without inflating the budget. general tolerance iso 2768-mk

This report outlines the application and specifications of the general tolerance standard, which is widely used in mechanical engineering to simplify technical drawings by providing standard tolerances for dimensions and geometric features that do not have individual callouts. 1. Scope and Application Applies to flatness
