ISO 8740:2025

Fasteners — Parallel grooved pins, with chamfer point — Full-length diamond grooves

This document specifies the characteristics of parallel grooved pins with chamfer point and full-length diamond grooves (with open ends), in steel and stainless steel, and with nominal diameter 1?mm to 25?mm.

These grooved pins are designed to fulfil the main following function: locking together two or more parts, with an easy installation (due to the chamfer point) and a highest 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 ISO?13669.
