Fasteners — Grooved pins — One-third-length center grooves (Edition 3, 2026)

Abstract
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 1 mm to 25 mm.

These grooved pins are designed to fulfil the main following functions:

relative rotation of the assembled parts, and
positioning 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 ISO 13669.
