    Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. 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.

    The tolerance values specified by the end-user are known as specification limits – the upper specification limit (USL) and lower specification limit (LSL). [2] If the process data plotted on a control chart remains within these specification limits, then the process is considered a capable process, denoted by C ^ p k {\displaystyle {\hat {C ...
