Here is the key information about DIN 7161:

In the field of mechanical engineering and manufacturing, precision is paramount. The ability to produce parts that fit together perfectly, especially when dealing with internal dimensions like holes, relies on standardized tolerance systems. is a historically significant German standard (Deutsches Institut für Normung) that defines the ISO allowances for internal dimensions (holes) for nominal dimensions ranging from 1 to 500 mm.

The standard aligns with ISO recommendations (specifically referencing ISO/R 286-1962), ensuring international compatibility in fitment. Key Characteristics of the DIN 7161 Standard Common Fits Defined by DIN 7161 : To

Unlike its sibling document DIN 7160 (which regulates deviations for shafts and external components), . This relies on uppercase fundamental tolerance symbols (e.g., H5, H6, H7, H11) to define the boundary limits of a bore. 2. Size Groupings (in mm)

The allowances in the standard tables are typically given in micrometers (μ m). Understanding DIN 7161 Tolerances (PDF/Table View)
