ABSTRACT:
An apparatus for coating internally threaded fasteners, particularly closed end fasteners, such as flanged weld nuts, which includes a powder spray arrangement, has a spray nozzle within a spray cylinder. The spray nozzle arrangement is actuated by an air cylinder to be in abutting relationship with a fastener seated in the spray position. The spray nozzle is tapped for the supply of air and for the supply of powder to the fastener threads. The spray block on which the nut is sprayed has a vacuum line that exhausts excess powder that does not adhere to the threads.
