) of the thread. For any given nominal diameter (e.g., M10, M12) and pitch, Form A prescribes the following crucial values: 1. Undercut Diameter ( : The official source for all DIN standards

Abrupt changes in shaft diameter create stress risers, which can lead to fatigue failure. The radiused corners of a Form A undercut distribute mechanical loads evenly.

) and lead angle specified in the DIN 76 standard. This saves programming time and guarantees compliance. Intended for technical reasons where space is limited;

: Manages dimensions specifically engineered for pipe threads conforming to international ISO 228-1 frameworks.

The actual dimensions vary based on the pitch of the thread. According to technical summaries often found in a DIN 76-1 PDF , standard values include: Metric Pitch ( Undercut Width (Normal/Form A) Undercut Diameter Where to Find the Official PDF

You can point a leader line to the thread shoulder and note:

DIN 76-1 is the German standard that specifies dimensions for and thread undercuts for ISO metric threads. It ensures that when a bolt is tightened into a tapped hole, it doesn’t bottom out or experience stress concentrations due to the transition between the threaded and unthreaded portion of the shank.
