EN ISO 8741:2025

This document specifies the characteristics of reverse-taper grooved pins with half-length progressive grooves (with closed ends), in steel and stainless steel, and with nominal diameter 1mm to 25mm.These grooved pins are designed to fulfil the main following functions:— positioning or guiding, and— relative rotation of the assembled parts,with an easy installation (due to its 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.
