ISO 286 fits

Enter the diameter and the fit — you get the limit sizes, clearance or interference and how to write it on the drawing.

Example: Ø 25 H7/g6 (sliding fit) → hole 25.000–25.021, shaft 24.980–24.993, clearance 0.007–0.041 mm.

Fits per ISO 286

Pick a common fit or set the hole and shaft tolerance yourself. Valid for nominal sizes up to 500 mm.

Common fits (hole basis)

    Limit deviations per ISO 286-1 and ISO 286-2. For critical parts check the values in the standard. A size on a range boundary (e.g. 30 mm) belongs to the lower range (18–30 mm).
