Iso | 2768-mh Tolerance Chart ((top))

Medium tolerance class for linear and angular dimensions .

For features smaller than 0.5 mm, tolerances must be indicated directly next to the dimension on the drawing. iso 2768-mh tolerance chart

Stands for the highest precision class under ISO 2768-2 . It defines limits for straightness, flatness, perpendicularity, and symmetry. ISO 2768-m (Linear Dimensions) Medium tolerance class for linear and angular dimensions

Notes:

Fictiv's CNC machining service adheres to the ISO 2768 tolerances, specifically meeting the medium requirements for precision. ISO 2768 General Tolerances Guide | PDF - Scribd It defines limits for straightness

| Nominal Hole Size (mm) | Tolerance Grade (implied) | Tolerance (± or +/–) | |------------------------|---------------------------|----------------------| | ≤3 | IT13 | +0.14 / 0 | | >3–6 | IT13 | +0.18 / 0 | | >6–10 | IT13 | +0.22 / 0 | | >10–18 | IT13 | +0.27 / 0 | | >18–30 | IT13 | +0.33 / 0 | | >30–50 | IT13 | +0.39 / 0 | | >50–80 | IT13 | +0.46 / 0 | | >80–120 | IT13 | +0.54 / 0 | | >120–180 | IT13 | +0.63 / 0 | | >180–250 | IT13 | +0.72 / 0 | | >250–315 | IT13 | +0.81 / 0 |

Note: For dimensions below 0.5mm, the deviation is generally specified directly on the drawing.
