Represents the International Tolerance (IT) grade, which defines the magnitude of the tolerance zone (e.g., 7, 6, 8). Smaller numbers indicate tighter tolerances. Clear tables providing upper (O) and lower (U)

Indicates the position of the tolerance zone relative to the zero line. Capital letters (A–ZC) are used for internal features (holes), while lowercase letters (a–zc) are used for external features (shafts). Indicates the position of the tolerance zone relative

When working with DIN 7161, consider the following extra quality aspects:

Understanding the history of DIN 7161 is crucial for using technical information correctly today. Like many standards, it has been revised and ultimately replaced by more up-to-date international versions as technology and practices have advanced. The standard was by DIN ISO 286-2:1990 (ISO system of limits and fits - Part 2: Tables of standard tolerance grades and limit deviations for holes and shafts). This newer standard incorporated the same ISO system but aligned more closely with the evolving ISO 286 series.
