ABSTRACT:
A self-flaring rivet and the method of making the same is disclosed. The end remote from the rivet head carries the swaging mechanism that is pulled outwardly to flare the end, inherently applying a tension force. This swaging mechanism also can be designed to remain in the rivet end or be pulled out completely. In the first instance the working stem of the swaging mechanism is broken off.
