Anotation

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 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
