standard byInternational Organization for Standardization , 03/01/2025
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 1mm to 25mm.
u000bThese grooved pins are designed to fulfil the main following functions:
u000b— positioning or guiding, and
u000b— relative rotation of the assembled parts,
u000bwith an easy installation (due to its shape) and a medium level of pull-out resistance (due to the elastic fit behaviour of the pin).
u000bThe general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.
