Abstract
A two piece rivet having a deflectable drive pin for retaining the drive pin in a partially inserted position between the expandable prongs of the rivet is disclosed. The deflectable drive pin includes a hole forming two parallel resiliently deflectable segments each having a radial nib resiliently urged against the head of the rivet in a central drive pin hole. Retention of the drive pin in the fully inserted position between the prongs is effected by a pair of spaced apart circumferential interrupted grooves on the pin receiving projections on inner surfaces of the rivet prongs.
