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, d 1 , from 1,4 mm to 20 mm inclusive. The displaced material to each side of the grooves forming an expanded diameter, d 2 , which is larger than the nominal diameter, d 1 , will cause a non-positive locking fit when these grooved pins are forced into a drilled hole equal to the nominal diameter d 1 (see clause 4 ).
