Annotation of standard text ČSN EN ISO 8742 (022175):

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
