International tolerance grade (IT) – the classification system – representing groups of … The ISO system uses an alpha-numeric code to illustrate the tolerance ranges for the fit, with the upper-case representing the hole tolerance and lower-case representing the shaft. For example, in H7/h6 (a commonly-used fit) H7 represents the tolerance range of the hole and h6 represents the tolerance … See more 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 … See more • Geometric dimensioning and tolerancing • Engineering tolerance • Interchangeable parts See more Overview The International Organization for Standardization system splits the three main categories into several individual fits based on the … See more Interference fits Interference fits, also known as press fits or friction fits, are fastenings between two parts in which the inner component is larger than the outer component. Achieving an interference fit requires applying force … See more diagramming example
