ABSTRACT:
The present invention has three arcuate prongs that are connected to a hub. The hub has a first end and a second end, and at least one end of the hub is circumferentially continuous. The hub second end is threaded. In one embodiment, the hub has a threaded outer surface. In another embodiment, the hub has a threaded inner surface. The prongs are manipulable, or bendable. Stress developed during manipulation of the prongs does not distort the threaded surface of the hub second end. An additional component can be threadably connected to the threaded surface of the hub second end. The circumferentially continuous portion of the hub acts as a barrier that prevents any excess laminate from contacting and bonding with the threads.
