HIGH SPEED LUGNUT SOCKET
A socket for driving a lug nut. The socket may include a tapered external surface which eliminates shoulders which might otherwise exist at the external surface of the socket. The tapered external surface may be formed as a sleeve. In a second implementation, the sleeve may both provide the tapered external surface and may also cover one end of the socket to increase the overall diameter and hence grippability of the socket. The socket may be fabricated from steel, while either of the sleeves may be fabricated from a lighter material such as aluminum or an alloy thereof. The socket may have a chamfer at the internal termination of the wrench surface of the socket to better seat lug nuts having a correspondingly tapered configuration.
1 . A socket for driving lug nuts, comprising a socket chamber bearing an internal wrench surface, and an outer surface devoid of discrete shoulders.
2 . The socket of claim 1 , wherein the socket chamber has a first cylindrical outer surface and the socket comprises an extension having a second cylindrical outer surface which is of a diameter less than that of the first cylindrical outer surface, the socket further comprising a sleeve adapted to make a tapered transition between the first cylindrical outer surface and the second cylindrical outer surface.
4 . The socket of claim 2 , wherein the socket is fabricated from steel, and the sleeve is fabricated from aluminum.
5 . The socket of claim 2 , wherein the sleeve both covers the first cylindrical outer surface and also makes the tapered transition to the second cylindrical outer surface from that portion of the sleeve covering the first cylindrical outer surface.
6 . The socket of claim 1 , further comprising a chamfer formed in the socket chamber.
7 . The socket of claim 1 , further comprising a spring.
8 . the socket of claim 7 , further comprising a set of springs of different lengths.
