ABSTRACT:
A socket wrench is provided which performs the functions heretofore carried out by two separate wrenches. To this end, the present invention provides a wrench where each end thereof selectively acts (a) as a receiving end for a nut or other fastener to be rotated by the wrench and of a different size than that to be received by the other end of the wrench and, (b) as the receiving end of a driver member which is to rotate the wrench to turn the nut or other fastener surrounded by the other end of the wrench. Preferably, the same driver member is insertable into either end of the wrench.
