Resin coated fastener and apparatus and method for manufacture of same

An apparatus for applying a resin coating to a plurality of discrete portions of a threaded fastener, comprising:

• a powdered resin reservoir;
• a first powdered resin spray assembly communicating with said reservoir and operable to generate a first air-borne powdered resin stream;
• a heater;
• a conveyor adapted to support said fastener and to move said fastener along a path which first passes adjacent to said heater and thereafter traverses said first resin stream to apply said resin coating onto one of said discrete portions of said fastener;
• a second powdered resin spray assembly operable to generate a second powdered resin stream to apply said resin coating to another of said discrete portions of said fastener, said second assembly having a resin receiver carried by said conveyor and positionable to traverse said first resin stream to generate a powdered resin supply for said second powdered resin stream.
