ISO Tolerance zone calculator Usage The calculator application page is divided into 3 windows Note: Hole based fits should be preferred. ex: 25 H11/c11 or separated with a dash ex: 25 H11-c11 Fits are either based on the hole feature or the shaft feature. ex: 25 H11 or 25 c11 A fit is defined by the basic size followed by the tolerance of each component. A feature tolerance is defined by the basic size followed by the tolerance designation. Upper case letters apply to holes or female type features.

- The minimum tolerance describes the smallest size the feature can be after the tolerance has been applied to the basic size.Ī lower case letters apply to shafts or male type features.

- The maximum tolerance describes the largest size the feature can be after the tolerance has been applied to the basic size.

ex: H11 Each tolerance has a maximum and minimum. The letter is the tolerance deviation, the number the tolerance grade. A tolerance is described using a letter followed by a number. British Standard for metric Limits and Fits General overview (all dimensions are millimeters) The basic size of the feature or fit is the dimension the tolerances will be applied to: The zero line in the calculator. Tolerances can be applied to holes and shafts as well as other shapes.
