Covers nominal dimensions from 1 mm up to 500 mm . din 7161 pdf
While DIN 7161 has formally given way to the international language of ISO 286, its structural logic remains embedded in the DNA of global manufacturing. Whether you are dealing with legacy blueprints or configuring CNC parameters for an H7/g6 clearance fit, understanding the underlying rules of fundamental deviations ensures your components will fit together perfectly every single time.

Metrologists use the tables to set pass/fail criteria on micrometers, air gauges, and Coordinate Measuring Machines (CMMs).
Lowercase letters. An "h" shaft has an upper deviation of zero, meaning the shaft can never be larger than the nominal size. 3. International Tolerance Grades (IT Numbers)
If your operational parameters mandate an official audit trail or an authenticated reference file, you can utilize the following platforms: Whether you are dealing with legacy blueprints or
The following chart illustrates the development of this standard family, from the historical DIN 7161 to the modern ISO standards used today:

In the world of manufacturing and mechanical engineering, precision is king. The interchangeability of parts, the ability to assemble components without rework, and the overall quality of a final product all depend on strict adherence to dimensional specifications. This principle is governed by the system of Limits and Fits. Before the widespread adoption of unified international standards, individual nations maintained their own comprehensive systems. For German industry, a key part of this historical framework was the standard , titled "ISO Allowances for Internal Dimensions (Holes) for Nominal Dimensions from 1 to 500 mm".
In the context of engineering, an "allowance" is a planned deviation from a nominal dimension, intentionally introduced to create different types of fits between mating parts. DIN 7161 provided the specific numerical values for these allowances for holes, which was crucial for:
