A device for delivery of fasteners having heads with tenons disposed beneath the heads to an insertion tool. The device includes a sloped track with two spaced-apart rails each having a fastener receiving surface to receive the undersides of the heads of the fasteners falling thereon. The fasteners drop onto the track from a rotating barrel and some are correctly aligned with the tenons between the rails and the undersides of the heads resting on the rails and many are misaligned. The fasteners slide to an orienting station which includes a plurality of fluid injector ports disposed around the track. Two of the ports face each other and a third port is disposed over the track. Blasts of air are directed through the ports sequentially so that misaligned fasteners on the track are forced into alignment or are removed from the track thereby leaving only properly aligned fasteners to proceed. A segregation station is disposed downstream of the orientation station to receive a supply of fasteners arriving in a continuous aligned row from the orientation station. The segregation station delivers a single fastener to a receiver for engagement by the insertion tool. The receiver receives the fastener and holds it in an operative relationship relative to the insertion tool. An air jet in the segregation station and a vacuum source in the receiver moves the fastener from the segregation station to the receiver.
