A socket drive in which a handle is connected to a cylindrical head with a roller clutch internally secured therein. A drive member is maintained within the roller clutch and includes a longitudinal passageway wherein a slidable extension member is lodged. The ends of the slidable extension member are connectable to the sockets. The drive member locks with the roller clutch when rotated in one direction such that torque applied to the handle is transmitted to the socket through the roller clutch, drive member, and slidable extension. In the opposite direction, the drive member turns freely in the roller clutch so that substantially no torque is transmitted to the socket.
