General Tolerance Iso 2768-mk !link! Jun 2026

If you write "±0.05" next to a dimension, that specific value overrides the general ISO 2768-mK class for that feature.

By following these guidelines and understanding the principles of general tolerance and ISO 2768-MK, you can ensure that your engineering designs are both precise and practical. general tolerance iso 2768-mk

Tighter tolerances (like ISO 2768-f) can be 2 to 2.5 times harder and more expensive to machine. The "mK" class offers a sweet spot between precision and production speed. If you write "±0

A 200 mm long milled surface under ISO 2768-mk must not warp by more than 0.2 mm (flatness). Its end face must be perpendicular to its base within 0.4 mm over the full length. general tolerance iso 2768-mk
