Abstract: Apparatus and method are provided for the continuous manufacture of self-locking internally threaded fasteners having a locking body or patch comprised of resilient thermoplastic material, applied to the fastener in powder form. A support member having a plurality of cavities for receiving said fasteners, and a nozzle associated with each of said cavities, is moved along a path through a plurality of locations wherein the fastener is deposited at a cavity aligned with a respective nozzle at a first location, material is forced through the nozzle onto the fastener at a second location, the fasteners are removed from the respective support at a third location, and the nozzles are purged of material at a fourth location prior to the initiation of a subsequent sequence of operations by the apparatus.
