<p>A socket tool is formed primarily from nonmetallic composite material. The socket tool body is compression molded to net shape using high strength, E-glass reinforced (60-65% weight random glass fibers approximately one inch long) vinyl ester sheet molding compound. Since it consists entirely of nonmetallic materials, the socket body demonstrates unique qualities, including being nonconductive, nonsparking, corrosion resistant, lightweight, nonmagnetic and low marring. The outer wall of the socket features a molded serrated finish texture, providing a convenient grip surface. The square drive end of the socket incorporates an insert-molded metal insert in order to bear the high contact stresses from a ratchet drive square. The metal insert is electrically isolated from the exterior walls and hex opening of the socket so as not to compromise the electrical insulating and nonsparking qualities of the tool. <IMAGE></p> |
