is a historical German technical standard that specifies ISO deviations for internal dimensions (holes) for nominal sizes ranging from 1 mm to 500 mm . Published in August 1965, it defines the fundamental tolerances and limit deviations—such as H7, H8, and G7—required for precision engineering and manufacturing.

The primary objective of DIN 7161 is to define the permissible limits of variation for internal dimensions, or "bores." In industrial manufacturing, no part can be made to an exact theoretical dimension. Instead, engineers use standards like DIN 7161 to specify: din 7161 pdf extra quality
