DIN 7161:1965-08 holds an important place in the history of mechanical engineering standards. It helped formalize the use of the ISO system for hole tolerances across German industry. Today, while it is a historical document, its legacy lives on in the modern DIN EN ISO 286-2 standard.
Represented by letters (upper-case for holes, lower-case for shafts) and numbers (the IT grade, indicating the accuracy level).
While is a classic, modern engineering projects typically use DIN ISO 286-2 . The older DIN 7161, however, is crucial for:
