The search for is not just about finding a table of numbers. It is about ensuring compliance, safety, and manufacturability. A modern, legally obtained PDF provides:
If you require the official, fully detailed engineering document for compliance or auditing purposes, you can obtain the official (which covers Form A external threads) directly through the Beuth Verlag website or the Deutsches Institut für Normung (DIN) portal. Many manufacturing and engineering software suites (like SolidWorks, Autodesk Inventor, and McMaster-Carr CAD libraries) also come pre-loaded with DIN 76-A configurations for automatic insertion into designs. If you are working on a specific design, let me know: din 76-a pdf
If you want, I can:
For example, if you are working with an M12 thread, you would reference the dimensions for the corresponding pitch (in this case, standard pitch is 1.75mm) within the DIN 76-A tables. In the technical diagrams found in these PDFs,
In the world of precision engineering and manufacturing, standardization is everything. When designing machined parts, especially shafts and threaded components, one of the most common yet frequently misunderstood requirements is the specification for .
Standardized depths and widths for undercut grooves based on pitch ( When designing machined parts
DIN 76 is the overarching standard that defines thread undercuts and thread run-outs for ISO metric screw threads. The standard is divided into different forms depending on the application and whether the thread is external or internal.

A standard DIN 76-A undercut consists of three main geometric elements: Undercut Diameter (
