ÖNORM EN ISO 7719

Issue date: 2025 09 15

Fasteners - Prevailing torque hexagon nuts - Regular nuts (all metal) (ISO 7719:2025)

This document specifies the characteristics of prevailing torque (all metal) hexagon regular nuts, in steel and stainless steel, with metric coarse pitch thread M5 to M39, and with product grades A and B. NOTE            These nuts are designed with an overall height hmin = mmin (as specified in ISO 898-2 and ISO 4032 for style 1) plus the prevailing torque feature. hmax has been established in function of hmin; therefore, the tolerance (hmax – hmin) does not follow the ISO code system for tolerances (IT system). If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-2 or ISO 3506-2.

Frequently Asked Questions about ÖNORM EN ISO 7719

What is a "Single-User Licence"?

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

How can I get involved in the further development of this standard?

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
