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 as a function of hmin, therefore the tolerance (hmax
hmin) does not follow the IT system. 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.
