1 Scope

This document specifies the characteristics of prevailing torque hexagon regular nuts (with non‑metallic insert), in steel and stainless steel, with metric fine pitch thread 8 mm to 39 mm, and with product grades A and B.

NOTE These nuts are designed with an overall height equal to m_min (as specified in ISO 898-2 and ISO 8673 for style 1) plus the prevailing torque feature. The height of the prevailing torque feature (h_max – m_min) 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.
