Din 7161 Pdf <100% Pro>

In mechanical engineering and manufacturing, defining every single dimension with a specific tolerance is impractical and would clutter technical drawings. To solve this, standards bodies have established "General Tolerances" to apply to dimensions that do not have individual tolerance specifications.

. Originally published by the German Institute for Standardization ( Deutsches Institut für Normung

In the quiet, dust-moted corner of a German machine shop in 1965, a young apprentice named Elias held a blueprint that seemed to defy the laws of physics. It called for a 50mm bore, but the machinist, a veteran named Hans, just grunted and tapped a worn, grey booklet:

It was developed by the Deutsches Institut für Normung (DIN), the German Institute for Standardization, and published on August 1, 1965. As an older standard, it has since been , meaning it is no longer maintained for new designs. din 7161 pdf

Engineers and machinists frequently look for a to keep reference tables on hand. A standard PDF contains: Date: March 23, 2026

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

): The values in the table are the deviation in micrometers from the nominal dimension. Example Interpretation: If you need to define a 40H740 cap H 7

"Herr Fischer, what is DIN 7161?"

The shaft is always smaller than the hole, allowing relative movement. H7/g6 (Precision running fit)
