Most comprehensive engineering handbooks contain copied versions of the DIN 76-A tables.

Perform a 360-degree revolve cut around the axis of the shaft to create the groove.

Before diving into the details of Form A, it is helpful to understand where DIN 76‑A fits in the larger family of German thread‑relief standards.

Specifically for pipe threads conforming to ISO 228-1.

The standard is divided into different forms depending on the application:

(officially titled "Thread run-outs and thread undercuts for metric ISO threads according to DIN 13" ) is a German industrial standard that defines the standard forms and dimensions of thread run-outs and undercuts for metric ISO threads. The Definitive Guide to DIN 76-A: Understanding Thread

This standard ensures that components can be screwed together seamlessly by providing a space—the "undercut"—where the threading tool ends its cycle, preventing interference from incomplete threads during assembly. Core Purpose and Function

Generally, the undercut width is approximately three times the thread pitch (

Form A remains the default "normal" specification. If a drawing simply says "Undercut per DIN 76" without specifying a letter, engineering protocol generally defaults to Form A. Summary for Implementation Core Purpose and Function Generally, the undercut width

To fully appreciate the value of the DIN 76-A PDF documentation, it helps to understand the two primary methods used to terminate a thread against a shoulder.

Most reputable mechanical engineering handbooks reproduce the DIN 76-A tables legally in their fasteners and threading sections.
