Rivets (17) are supplied from a source via tube (22) and are delivered to the rivet delivery passage (12) by a rivet supply passage (20). The head of the rivet (17) is engaged by spring-loaded balls (60) to hold the rivet (17) in alignment with the rivet delivery passage (12) and a punch (16). When a limit switch (30) detects the presence of a rivet (17) in the rivet delivery passage (12), the punch (16) is advanced and the rivet (17) is releasably supported by the balls (60) and secondary balls (60A) as it is advanced to work pieces to be secured together.
