Nozzle Only for a specially engineered system for installing wood plugs in decks, flooring and woodworking applications. The Pro Plug Smart Bit (# HC-5011 purchased separetly)creates the screw hole with a countersink that is perfectly matched to Pro Plug Fasteners and plugs. The patented glue tip design coats the sides of the hole only, so very little if any glue winds up on the bottom of the hole. Plugs are made of real wood, meaning they fade at the same rate as the decking or flooring wood you use. The system creates easy insertion and an extremely tight fit since the plug compresses around the top of the hole for complete insertion without having to saw or chisel off the top. Imported.
