ABSTRACT:
A threaded fastener is made of a composite material made of layers extending parallel to the fastener axis and having elongated filament fibers. A portion of the fibers extend parallel to the axis of the fastener to provide tensile and shear strength to the fastener, and a portion of the fibers extend parallel to the load-bearing thread faces to enhance tensile strength to the threads.
