Anotace obsahu normy

This document specifies the characteristics of parallel grooved pins with half-length diamond grooves (with closed ends), in steel and stainless steel, and with nominal diameters 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 a more significant insertion force (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.
