Grooved pins with countersunk head. | Status: Superseded, Withdrawn

1 Scope This International Standard specifies the characteristics of countersunk head grooved pins which have three equally spaced grooves impressed longitudinally on their exterior surface, with nominal diameter, d1, from 1,4 mm to 20 mm inclusive. The displaced material to each side of the grooves forming an expanded diameter, d2, which is larger than the nominal diameter, d1, will cause a non-positive locking fit when these grooved pins are forced into a drilled hole equal to the nominal diameter d1 (see clause 4).
