ABSTRACT:
A wrench socket that has a driven end for receiving a driving wrench in an internal or female drive opening, a driving end for engaging a threaded fastener to transmit a driving torque to the fastener and an intermediate external or male drive surface area which can be engaged by a second driving wrench. A removable retaining member is provided to assure that the second wrench is held on the socket, and a series of sockets may be provided which have various sized driving ends, but all have identical sized female drive openings and identical sized male drive surface areas so that only a single sized first wrench or a single sized second wrench need to used to drive a range of sizes of threaded fasteners. The driving end can be in any form, such as a castellated opening, a female hex-shaped opening or a male hex-shaped projection.
