Technical Examples

An apparatus for the application of a fluoropolymer coating to the threads of an internally threaded fastener. The fastener has a body and a threaded bore extending to opposing ends of the body to define opposing first and second openings in the fastener. A conveyor moves the fastener along a path of travel with its threaded bore in a predetermined orientation. An obstruction member closes, the first opening, while a nozzle directs an air stream carrying entrained fluoropolymer powder through the second opening and into the threaded bore. The nozzle is stationary and is located at an axially displaced position relative to the second opening of the fastener and immediately adjacent the conveyor. A heating station heats the fluoropolymer powder to its melting temperature causing it to melt and fuse into a generally continuous film covering the fastener's threads.
