Iso 2768-mh Tolerance Chart 'link' Today

The is where things get interesting—and often misunderstood. It stands for Coarse accuracy regarding geometry (straightness, flatness, perpendicularity, symmetry).

It provides a universal language for manufacturers and clients globally, reducing the risk of misinterpretation .

: Represents the High/Tight tolerance class for geometrical features (such as flatness, straightness, parallelism, and symmetry) [1, 4].

These tolerances apply to measurements like lengths, widths, diameters, and step distances. Nominal Dimension Range (mm) Tolerance (± mm) Over 3 to 6 Over 6 to 30 Over 30 to 120 Over 120 to 400 Over 400 to 1,000 Over 1,000 to 2,000 Over 2,000 to 4,000 Xometry Standard Tolerances Geometrical Tolerances (H - High Precision)
