Fasteners — Prevailing torque hexagon nuts — High nuts (all metal), with fine pitch thread

SKU: 4c79ad11a8b3 Categories: ,

Description

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 hmin = mmin (as specified in ISO 898-2 and ISO 8674 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.
