ISO 8675:2023, Fasteners — Hexagon thin nuts (style 0), with fine pitch thread

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.
