1 Scope
This part specified the characteristics of the grooved pins with round head which have three equally spaced grooves impressed longitudinally on their exterior surface, with nominal diameter d1 from 1.4mm to 20mm 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 Chapter 4).
