ISO 7041:2025 Scope

This document specifies the characteristics of prevailing torque hexagon high nuts (with non‑metallic insert), 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 equal to mmin (as specified in ISO 898-2 and ISO 4033 for style 2) plus the prevailing torque feature. The height of the prevailing torque feature (hmax – mmin) for the non-metallic insert is identical for regular, high and thin nuts for a given diameter.

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.
