Iso 2768-mh Tolerance Chart ((new)) Jun 2026

Angular tolerances for untoleranced dimensions are not absolute degrees. They depend on the length of the legs. A short 5mm chamfer at 45° can deviate by 1°, while a long 200mm angled brace can only deviate by 0°5'.

The "h" class defines the general tolerances for geometric characteristics. : Up to 10 mm: 0.1 mm 10 to 30 mm: 0.2 mm 30 to 100 mm: 0.4 mm 100 to 300 mm: 0.8 mm 300 to 1000 mm: 1.2 mm iso 2768-mh tolerance chart
