ISO 8745:2025

Fasteners — Taper grooved pins — Half-length progressive grooves

This document specifies the characteristics of taper grooved pins with half-length progressive grooves (with close-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 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 ISO 13669.
