DIN 76A is a German standard for a specific type of threading, known as a "Metric Thread with a 60-degree angle and a flat crest." The standard is published by the Deutsches Institut für Normung (DIN), a German national standards body. DIN 76A defines the dimensions, tolerances, and testing methods for metric threads with a 60-degree angle and a flat crest.

Understanding the DIN 76 Standard for Thread Run-Outs and Undercuts
Thread run-outs (also known as thread run-outs or run-out lengths) are critical because:
HEIDENHAIN MANUALplus and SINUMERIK CNC controls include built‑in . When called, the control determines the appropriate undercut parameters directly from the thread pitch and machines the groove and thread chamfer in a single operation. The entry angle can be freely selected within the 30° to 90° range. DIN 76A is a German standard for a

When a thread is cut or rolled onto a cylindrical shaft, the cutting tool cannot stop instantly at a sharp 90-degree shoulder. This creates a "thread run-out"—a section of imperfect, shallow threads near the shoulder.
