Legally, no. DIN standards are copyrighted technical documents. However, many reputable engineering reference handbooks (e.g., Machinery's Handbook , Roloff/Matek Maschinenelemente ) summarize the critical tables of DIN 76-A. For quick workshop reference, laminated summary charts are often available from third-party vendors. But for legally binding design work, you must purchase the official PDF.

While you should always consult an official DIN 76-A PDF chart for precise manufacturing tolerances, here are the standard dimensions for common metric thread pitches: Thread Pitch ( Undercut Diameter ( Undercut Width ( Undercut Width ( Corner Radius ( (e.g., M3) 0.7 mm (e.g., M4) 0.8 mm (e.g., M5) 1.0 mm (e.g., M6) 1.25 mm (e.g., M8) 1.5 mm (e.g., M10) 1.75 mm (e.g., M12) 2.0 mm (e.g., M16) 2.5 mm (e.g., M20)

DIN 76-1 is a standard established by the German Institute for Standardization ( Deutsches Institut für Normung ). It defines the dimensions for thread run-outs, thread undercuts, and thread ends for ISO metric screw threads. din 76-a pdf

If you are looking for the actual PDF documentation or detailed tables, you can find them on various technical hosting sites:

The standard clearance undercut used for general engineering applications. It is suitable for normal load distributions. Legally, no

Understanding the structure of the official PDF can help you find the specific information you need quickly. The table of contents from a representative version (DIN 76-1:2016-08) outlines the document's systematic organization [10†L2-L8]:

Specifies the standard dimensions for external thread undercuts (bolts, studs, and screws). For quick workshop reference, laminated summary charts are

For ISO metric threads (coarse and fine pitch), covering both external and internal undercuts. DIN 76-2: For pipe threads conforming to ISO 228-1.
