6/15/2023 0 Comments Iso fits and tolerances chart![]() ISO and ANSI both group fits into three categories: clearance, location or transition, and interference. ISO is the internationally accepted standard for defining engineering fits, but ANSI is often still used in North America. Engineering fits are generally described as a "shaft and hole" pairing, but are not necessarily limited to just round components. In engineering terms, the "fit" is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined.
