1 Scope

This document specifies the characteristics of prevailing torque (all metal) hexagon high nuts, 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 h_min = m_min (as specified in ISO 898-2 and ISO 8674 for style 2) plus the prevailing torque feature. h_max has been established in function of h_min; therefore, the tolerance (h_max – h_min) does not follow the ISO code system for tolerances (IT system). The wrenching height m_w,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.
