A fastener (100) slides down a tube (12) onto one end of a channel (16) formed in a V-shaped block (14). Movement of the fastener (100) along the channel (16) is retarded by two fingers (20, 26). A blade (38) moves along a slot (18) in the bottom of the channel (16) to push the fastener (100) along the channel (16) past a feeler (56). The feeler (56) is attached to a shaft (60) of a rotary transducer (58) to pivot therewith. A linear transducer (50) is actuated by longitudinal movement of the blade (38). The output of the transducers (50, 58) is compared by a computer to a predetermined output to check the profile of the fastener (100). A carriage (68) is moved to bring the infeed end (72) of a conduit (70) adjacent to the outfeed end of the block (14). The blade (38) pushes the fastener (100) into the conduit (70).
