Preliminary reference information. Confirm the current standard, material, process capability, surface finish, and inspection method before specifying a fit.
Method and dataset scope
Hole-basis H7 with g6, h6, n6, or p6 shaft zones only, using the small diameter-range table in the tested local ISO-fit kernel. Deviations are applied to the nominal diameter in micrometres; no value is interpolated or invented.
