Metrologists use the tables to set pass/fail criteria on micrometers, air gauges, and Coordinate Measuring Machines (CMMs).

Bearings pressed into housings, gear wheels on shafts. Common ISO designations: H7/p6 or H7/r6. 3. Transition Fits

It is important to note that has been largely withdrawn and replaced by newer international standards, specifically ISO 1938-1 , which governs "Plain limit gauges of linear size." [1, 3]

Because DIN 7161 is an old, withdrawn standard, obtaining it is not as straightforward as accessing a modern one. din 7161 pdf

Defines the ISO system of limits and fits specifically for internal features (holes). Size Range: Covers nominal dimensions from 1 mm to 500 mm .

The exact for a specific size (e.g., 20mm H7/g6)

This standard provides comprehensive tolerance tables for internal dimensions (holes). Its primary function is to define the maximum and minimum allowable deviations—measured in microns—for various size groups across a range of 1 mm to 500 mm. Current Status DIN 7161 is a withdrawn and superseded document. Metrologists use the tables to set pass/fail criteria

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

It serves as a critical reference for machinists and quality control teams to ensure that "fits" (the relationship between a hole and a shaft) are consistent, whether they are meant to be a loose clearance fit or a tight interference fit.
