If you are looking for a , you are likely dealing with legacy technical drawings, mechanical engineering education, or the maintenance of classic machinery.
The basic size of the part specified on the technical drawing. For example, a 30 mm shaft has a nominal size of 30 mm. 2. Actual Size din 7161 pdf
DIN 7161 establishes three primary types of engineering fits based on the relationship between the hole and shaft tolerance zones: 1. Clearance Fits
He explained that in the 1970s and 80s, West German industry had a problem. They had two parallel universes of general tolerances: the older, highly detailed for linear dimensions (like lengths, steps, chamfers) and DIN 7162 for angles and radii. These were practical, house-made standards.

However, if you are searching for a "DIN 7161 PDF" to use in modern engineering, there are critical status updates and standard transitions you need to be aware of. 📉 Status of DIN 7161: Withdrawn and Superseded
"You can’t just drill a hole, Elias," Hans said, his voice gravelly. "You have to respect the limits and fits
DIN 7161 is a German standard that specifies dimensions, tolerances, and technical requirements for metric threaded pins (Gewindestifte) with hexagon socket (internal wrenching) or similar small threaded fasteners used primarily as set screws, locating pins, or for securing components without a head. It defines form factors, thread engagement lengths, permissible deviations, surface treatments, and marking where applicable. The standard ensures interchangeability and reliable mechanical function in assemblies across industries such as machinery, automotive, and tooling. The basic size of the part specified on
DIN 7161 is a standard published by the Deutsches Institut für Normung (German Institute for Standardization). It outlines the system of limits, tolerances, and fits for sizes ranging up to 500 mm. Specifically, it provides the fundamental data, deviation tables, and systemic rules for matching holes (internal features) and shafts (external features).
This indicates that for a nominal hole size of, say, 12 mm, the hole diameter must be between 12.000 mm and 12.018 mm.
DIN 7161 is a German standard developed by the Deutsches Institut für Normung (DIN) that defines the dimensional tolerances for plain cylindrical parts, such as shafts, holes, and cylindrical surfaces. The standard provides a set of rules and guidelines for specifying and verifying the dimensional accuracy of these parts.
