This document specifies the general characteristics of grooved pins, made of steel and stainless steel, with nominal diameters 1 mm to 25 mm.
These grooved pins are designed to fulfil the main following functions, due to the elastic fit behaviour of the grooves:
—     locking of two (or more) parts,
—     positioning or guiding,
—     relative rotation of the assembled parts.
