Abstract of the Disclosure For use in pull-through blind riveting a plurality of tubular rivets is received on a reuseable mandrel having a head and a stem, each rivet having a recess in its tail end which can accommodate a ring of metal separated by the mandrel head from the internal wall of the rivet set in a previous rivet-setting operation. Dimensions of the mandrel and its rivets insure that a complete ring rather than a crescent-shaped fragment is removed from the rivet being set, and this ring is caused to be retained in the recess of the next rivet to be set by the mandrel. In practicing the novel method, the separated ring of rivet metal is retained on the mandrel stem until the mandrel head is pulled through the ring in setting the next rivet.
