A fastening machine (1) has guide block (11) with a rivet delivery passage (12). 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.

[ We claim:] [1.] A fastener actuator for a fastening machine, wherein the actuator advances a fastener toward a workpiece for securing the fastener to the workpiece, comprising:means defining a fastener delivery passage downwardly through which the fastener passes,a fastener supply passage for sequentially delivering fasteners to the fastener delivery passage, and whereinthe fastener actuator is vertically movable through the fastener delivery passage, the actuator including a nose at its leading end for engaging a fastener and advancing the same toward the workpiece, the actuator being provided with an internal passage one end of which is open to the nose of the actuator and another end of which is connected to a vacuum source through a control, whereby connecting the internal passage to the vacuum source effects vacuum retention of the fastener on the nose of the actuator to maintain orientation of the fastener as the actuator advances toward the workpiece.
