This document specifies the characteristics of reverse-taper grooved pins with one quarter-length progressive grooves on both sides (with closed ends), in steel and stainless steel, and with nominal diameters 2mm to 25mm.
u000bThese grooved pins are designed to fulfil the main following functions:
u000b— relative rotation of the assembled parts,
u000b— locking of two (or more) parts
u000bwith 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).
u000bThe general requirements (including functional principles for grooved pins and assembly) are specified in ISO13669.
