ISO International Standard

This document specifies the characteristics of hexagon thin nuts (style 0), in steel and stainless steel, with metric fine pitch thread 8 mm to 64 mm, and with product grades A and B.

Thin nuts used as jam nuts are to be assembled together with a regular or high nut.

WARNING — Thin nuts (style 0) have a reduced loadability compared to regular nuts or high nuts, and are not designed to provide resistance to thread stripping (see ISO 898–2).

If in certain cases other specifications are requested, stainless steel grades and property classes can be selected from ISO 3506–2.
