WebTolerance: The difference between the maximum and minimum size limits of a part. Fit: Relationship between an external feature of size and an internal feature of size (the hole … In engineering, we have to define the tolerances of parts to ensure a long lifespan and proper working of a machine. We can choose the fits according to the necessities and working conditions. The three main categories are: 1. Clearance fit 2. Transition fit 3. Interference fit All these come with another subset of categories, … See more With engineering fits, the tolerance will always be shown in an alpha-numeric code. For example, a hole tolerance may be H7. The capital letter signifies that we are dealing with a hole. When indicating tolerance for a shaft, … See more When choosing a system for a fit, you have 2 options – hole and shaft system.

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.
