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 ISO898-2 and ISO4032 for style1) 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.
