The apparatus and method is directed to a pair of self-tapping, interconnecting, externally and internally threaded devices that, when installed between two separate pieces of material, will draw and hold the material together as a single threaded unit. While the pair of threaded devices are being fastened into the host material, due to the unique design of their threads, no radial outward forces are produced that could cause cracking or splitting of the sections of the material into which they are installed. The external threads are helically defined into the exterior of each half of the device with a right hand thread defined into one half and a left hand thread into the other half. When the two halves are being fastened together, the increased thread pitch on one of the halves continuously draws the halves into each other even when the internal threads have already been maximally tightened.
