The table shows the limit deviation for the hole (e.g., 0 to +18μm for a specific size).
Using the ISO 286-2 tables, you can determine the exact upper and lower limits:
The ISO 286 PDF can be downloaded from the official ISO website or purchased from authorized distributors. It is essential to ensure that you are accessing the standard from a reputable source to guarantee its accuracy and authenticity.

Because ISO 286 is a copyrighted standard, official, fully updated copies should be purchased directly from the official , national standards bodies (like ANSI, BSI, or DIN), or authorized engineering document distributors. Many engineering handbooks and CAD software suites also integrate interactive versions of the ISO 286 tables directly into their systems for faster calculation. The table shows the limit deviation for the hole (e
Implementing the ISO 286 system removes ambiguity from engineering drawings. By ditching arbitrary +/- tolerances and adopting the global standard, companies benefit from:
A fit is defined by combining the hole and shaft tolerance codes. The format is typically (e.g., H7/g6). The number indicates the IT grade, and the letter indicates the fundamental deviation. This code provides a complete description of the fit's clearance or interference.
Fundamental deviation h means the upper deviation is zero. You need a sliding fit for a 40
ISO 286 is a two-part international standard developed by the International Organization for Standardization (ISO). It provides a globally accepted system of tolerances and fits for linear dimensions of cylindrical and flat features (such as shafts and holes). The standard is divided into two distinct parts:
Standardized plug gauges and snap gauges can be mass-purchased to match standard ISO 286 fit sizes, speeding up inspection loops.
Without ISO 286, manufacturing would be chaotic. A shaft made by Company A might not fit into a hole made by Company B, even if both claim the diameter is "20 mm." The ISO 286 system ensures —the ability to replace a broken part with a new one without custom modification.
This part provides tabulated numerical data for limit deviations based on the nominal size of the part (up to 3,150 mm). Key Components of the ISO 286 System
If you have ever found yourself searching for an "ISO 286 PDF," you are likely looking for the official documentation of the ISO system of limits and fits. Whether you are designing a press-fit bearing, a sliding shaft, or a clearance fit for a hydraulic cylinder, ISO 286 is your blueprint.
