Din 7161 Pdf ((full)) Guide

DIN 7161, titled "ISO-Abmaße für Innenmaße (Bohrungen) für Nennmaße von 1 bis 500 mm" (ISO deviations for holes for nominal sizes from 1 to 500 mm), was first established in 1965. It provides standardized tables for hole tolerances, allowing engineers to specify the exact permissible variation for internal features to ensure proper assembly with mating shafts.

Indicates the position of the tolerance zone relative to the nominal size (zero line). For example, "H" indicates the lower limit is exactly the nominal size. You generally have two paths: Official Purchase :

: While many engineers still search for DIN 7161, it has largely been integrated into or replaced by Core Content : While many engineers still search for DIN

DIN 7161 was officially withdrawn and replaced to align with global standards. If you are looking for the modern equivalent, you should refer to:

However, the name DIN 7161 persists. Many older engineers continue to use the term, and the specific numerical tables are often more practical for clearance fits than the broader ISO equivalents.
