The standard is typically divided into sections based on the type of thread:

The dimensional accuracy of threads only starts with the third pitch, meaning the "no‑go gauge" may be inserted or screwed on up to this length—a practical consideration that directly influenced the development of the standard.

When Form B is necessary, include a clear note on the drawing explaining why the short undercut is required, and verify that your manufacturing partner has the special tooling needed to produce it.

The current standard is – Thread run-outs and thread undercuts for metric ISO threads according to DIN 13 . If you meant DIN 76-2 , that covers thread run-outs and undercuts for fine pitch threads. The standard is typically divided into sections based

When drafting your next 3D model or 2D technical drawing, remember to explicitly call out the undercut form. A standard drawing note or CAD feature label usually reads: . This tells the machinist exactly which groove profile to apply, ensuring your threaded assemblies function perfectly. If you are setting up a manufacturing run, tell me: What specific metric thread size are you working with? Are you using coarse or fine pitch threads?

Some engineering forums and educational sites host scanned copies of the of DIN 76a. While these are not the current standard (always check the year of issue), they are often used for legacy machine designs. Search for "DIN 76a 1981 PDF" cautiously. If you meant DIN 76-2 , that covers

A typical data sheet found within a DIN 76-A PDF provides specific dimensions tied strictly to the pitch (

is the German industrial standard that defines dimensions for thread run-outs and thread undercuts

when you require a tight, flush assembly with zero gap between the component shoulder and the mating face. It is ideal for precision machinery, fluid fittings, and adjusting screws. However, be aware that the reduced diameter (
