ABSTRACT:
A unique connector and insertion tool are disclosed. The connector is hollow with screw-type threads on its outer surface, an enlarged head at one end and a non-sharp configuration at the other end. The insertion tool has a non-sharp elongated shaft or piercer attached to a handle; the end of the piercer is adapted to allow piercing and passage through the materials being secured together. The connector slides over the piercing shaft, is held in secure non-rotating relation thereto, and is configured to penetrate the materials and be screwed into place by the insertion tool. The entire piercing and connection operation may be conducted in a twisting motion with just one hand.
