Iso 2768-mh Tolerance Chart !free! Jun 2026
Why would an engineer specify "mh" instead of a tighter "ff" (fine/fine) or a looser "cL" (coarse/coarse)?
Perpendicularity requires a feature to be at a precise 90-degree angle relative to a datum surface. Nominal Length of Shorter Leg (mm) Perpendicularity Tolerance (Class H) Over 100 to 300 Over 300 to 1000 Over 1000 to 3000 6. Symmetry and Run-out (ISO 2768-2, Class H) iso 2768-mh tolerance chart
"mH" represents a combination of from Part 1 and High (H) from Part 2. This is one of the most common combinations used in general engineering, balancing manufacturing capability with functional requirements. 2.
