Scope

This document specifies design criteria for nuts specified in ISO 898-2 so that, under static tensile overload, the stripping fracture mode is prevented.

The design criteria are also applicable to non-standardized nuts or internally threaded elements with ISO metric screw threads (in accordance with ISO 68-1) mating with bolts. However, dimensional factors such as the width across flats or other features related to rigidity of nuts, and thread tolerances can affect the load ability of the individual bolt and nut assemblies. Therefore, it is intended that verification tests be carried out

Purpose

Note : This CEN WI is requested to develop ISOAWI 16224, ISO id 84884, under the Vienna Agreement process (ISO lead)

Note: in case the WI is based on documents from other organizations than ISO/IEC, please specify it here
