EN ISO 8742:2026

This document specifies the characteristics of grooved pins with one-third-length centre oval grooves (with closed ends), in steel and stainless steel, and with a nominal diameter from 1mm to 25mm.These grooved pins are designed to fulfil the main following functions:relative rotation of the assembled parts, andpositioning or guiding,with an easy installation (due to its symmetrical shape) and a medium level of pull-out resistance (due to the elastic fit behaviour of the pin).The general requirements (including functional principles for grooved pins and assembly) are specified in ISO13669.
