Intended for technical reasons where space is limited; typically requires special tools for manufacturing. Key Dimensions:

) slightly lowers the tensile strength of the bolt at that specific cross-section.

Yes. The standard applies equally to right‑hand and left‑hand ISO metric threads. The geometry of the run‑out or undercut does not depend on the hand of the thread. din 76a pdf

: Used in pumps and pressure vessels to ensure safety under high-pressure conditions. How to Find a DIN 76-A PDF

A gap remains between the mating part and the component shoulder. Intended for technical reasons where space is limited;

This article serves as a comprehensive resource. We will explain what DIN 76a is, why it is essential, how to interpret its tables, and—most importantly—how to obtain and use a legitimate in your daily work.

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 standard applies equally to right‑hand and left‑hand

(bolts/screws). It is used when there are no strict space limitations. : A "short" design for external threads

When creating engineering drawings, you do not need to manually draw every detail of the undercut if you utilize standard callouts. Drawing Symbols

DIN 76‑1 is a German industrial standard titled “Fasteners – Thread run‑outs and thread undercuts – Part 1: For ISO metric threads in accordance with DIN 13‑1.” It specifies the dimensions and designations for thread run‑outs and thread undercuts on both external threads (e.g., bolts and screws) and internal threads (e.g., blind tapped holes). The standard applies to ISO metric coarse and fine pitch threads as defined in DIN 13‑1 and DIN ISO 261.

When looking at a DIN 76A data sheet, the dimensions of the undercut are fundamentally linked to the of the metric thread.
