The standard provides tables where the tolerance value is determined by the . As the dimension size increases, the allowable tolerance deviation increases.
Historically, DIN 7161 was the bedrock of the (German Fit System), ensuring that a shaft manufactured in one factory would perfectly mate with a hole bored in another. The Evolution: DIN 7161 vs. ISO 286 Date: March 23, 2026

DIN 7161 is a German standard that specifies tolerances for linear and angular dimensions of metallic materials. The standard is published by the Deutsches Institut für Normung (DIN), which is the German national body responsible for developing and publishing technical standards.
The shaft is always larger than the hole. Parts must be pressed together. Permanent assemblies, bearing bushings. Structure of a DIN 7161 PDF Data Table
Servicing defense, aerospace, or heavy industrial infrastructure that requires strict adherence to the original design blueprints.
The primary purpose of DIN 7161 was to define the (allowances) for hole sizes ranging from 1 mm to 500 mm. These values are typically expressed in micrometers (
