General Tolerance Iso - 2768-mk ((full))

Section C 10. Ø12 H7 explicit callout controls; ISO 2768 does not override an explicit tolerance. H7 defines specific limits (hole basis tolerance); general tolerance ignored for that dimension. 11. Not acceptable for precision fit; drawing must specify tolerances (e.g., shaft Ø19.98–20.00 and bore Ø20.02–20.05) or use fit designation (e.g., H7/g6) to guarantee 0.02–0.05 mm clearance. 12. Consequences: possible assembly interference or functional failure; actions: reject/ rework part or negotiate acceptable nonconformance and update drawing tolerance notes; implement supplier corrective action.

For linear measurements like external/internal sizes, heights, and distances. Nominal Range (mm) Tolerance (± mm) 120 to 400 400 to 1000 Geometric Tolerances (Class K) general tolerance iso 2768-mk
