Abstract
This document specifies the characteristics of grooved parallel pins with half-length diamond grooves (close-ends), with rounded or chamfered pin ends, in steel and stainless steel, with nominal diameters 1 mm to 25 mm. These grooved pins are designed to fulfil the main following functions: — positioning or guiding, — relative rotation of the assembled parts. The general requirements (including principles for grooved pins and assembly) are specified in ISO 13669.
