Iso 2768-mh Tolerance Chart

Before diving into the chart, it’s important to understand the standard itself. ISO 2768 is divided into two primary parts:

Defines tolerances for form and position (e.g., flatness, perpendicularity, symmetry). Classes: H (fine), K (medium), L (coarse). "ISO 2768-mh" means the drawing uses: Part 1: Medium (m) for linear and angular dimensions. iso 2768-mh tolerance chart

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) Before diving into the chart, it’s important to
