Abstract

This document specifies the characteristics of prevailing torque (all metal) hexagon high 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 heigth hmin = mmin (as specified in ISO 898-2 and ISO 4033 for style 2) 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). The wrenching height mw,min corresponds to the values specified for style 1. 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.
