TS EN 25967

TS EN 25967 is a terminology standard for taps and thread cutting, focusing on the naming of the main tap types and the related technical vocabulary. It addresses the symbolisation of the principal tap types, together with the terminology used for their tool sets, dimensional characteristics, and thread profiles. In practice, this gives manufacturers, users, and technical authors a common language for identifying and comparing tapping tools.

How tap terminology is organised

The main value of the standard is that it links varied commercial and manufacturing terminology to a shared technical framework. Taps are cutting tools used to form internal threads, and their geometry, thread form, and size characteristics can differ according to the application. The diagrams and terms included in the standard help describe that variety; generally speaking, they are for terminology and identification rather than a full design specification for every manufacturer’s tool.

Language coverage and technical use

Based on ISO 5967, the document provides terms in the three official ISO languages and also equivalent terms in German and Italian. This makes it useful for catalogues, procurement descriptions, engineering drawings, training material, and multilingual technical communication. In general technical context, the thread profile is a key factor in selecting the tap, because the thread form influences compatibility with the intended fastener or threaded connection.
