In modern manufacturing, precision is not just about making a part "exact" but about controlling how much it can vary while still functioning. provides the internationally accepted framework for this control, specifically targeting cylindrical surfaces and parallel plane surfaces. By defining standardized tolerance grades and fundamental deviations, it eliminates the ambiguity of custom-designed fits and enables global interchangeability. 1.

ISO 286 defines the Geometrical Product Specifications (GPS) for tolerances on linear sizes. It provides a standardized system of tolerances, deviations, and fits for cylinders and two parallel opposite surfaces (e.g., holes, shafts, keys, and slots).

ISO 286 ensures that parts manufactured by different suppliers or in different countries can be assembled without modification — a critical requirement for global supply chains.

The number dictates the size of the tolerance zone (the accuracy).
