Fixations — Goupilles cannelées progressives — Cannelures progressives sur toute la longueur

Abstract / scope

This document specifies the characteristics of taper grooved pins with full-length progressive grooves (with closed end at the insertion side), 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 its shape) and a high 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.
