Iso 2768-mh Tolerance Chart Jun 2026

Applies to dimensions where no individual tolerance is specified.

This defines the tolerances for geometrical characteristics (flatness, straightness, symmetry). The "h" stands for High (the strictest level for geometry). Part 1: ISO 2768-1 (Linear Dimensions) iso 2768-mh tolerance chart

The designation is split into two distinct parts that cover different aspects of a part's geometry: m (Medium): ISO 2768-1 , which defines general tolerances for linear and angular dimensions . It is the most common class for standard machining. ISO 2768-2 , which covers geometrical tolerances like straightness, flatness, and perpendicularity. The Linear Tolerance Chart (m) For a drawing labeled ISO 2768-m Applies to dimensions where no individual tolerance is

In the world of mechanical engineering and manufacturing, a drawing is a legal contract between the designer and the machinist. But what happens when a dimension on that drawing has no explicit tolerance value listed next to it? Part 1: ISO 2768-1 (Linear Dimensions) The designation

When a drawing specifies "ISO 2768-mh," it refers to two distinct parts of the standard:
