Fasteners - Prevailing torque hexagon nuts - Thin nuts (with non-metallic insert)

This document specifies the characteristics of prevailing torque hexagon thin nuts (with non metallic insert), in steel and stainless steel, with metric coarse pitch thread M3 to M39, and with product grades A and B. NOTE These nuts are designed with an overall height equal to m min (as specified in ISO 898-2 and ISO 4035 for style 0) plus the prevailing torque feature. The height of the prevailing torque feature ( h max – m min ) for the non-metallic insert is identical for regular, high and thin nuts for a given diameter. Nuts with sizes D M5 and design principles in accordance with style 0 are specified in Annex A. WARNING — Thin nuts (style 0) have a reduced loadability compared to regular or high nuts, they 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.

Fasteners - Hexagon thin nuts (style 0)

This document specifies the characteristics of hexagon thin nuts (style 0), in steel and stainless steel, with metric coarse pitch thread M1,6 to M64, 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 .

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 .
