ABSTRACT:
An apparatus and method for providing a masking, insulating and/or lubricating barrier coating on a portion of the threads and/or other surfaces of discrete objects such as fasteners utilizing a liquid coating material as provided. The present invention can selectively coat threaded and/or unthreaded surfaces of fasteners having odd shapes, deep threads and extended hubs. The fasteners are subsequently elevated and inverted onto a conveying system that moves them away from the area where the coating material is applied directly into a heat treatment device such as an oven in a continuous on-line process that does not require manual handling of the fasteners.
