ABSTRACT:
An improved four-way socket wrench includes elongated socket members having a lower tubular portion connected between a socket head portion and a cross bar member, the lower tubular portion having an axial bore therein that is in communication with the socket opening of the socket member. Rigid implements can be inserted into the socket member so as to impart increased leverage thereto so as to, in turn, impart increased rotational torques to a nut being tightened or loosened.
