A hinged socket wrench having an offset shank (20) with a first end (22) and a second end (24). Attached to the first end (22) is a clevis (28) which receives a drive head that is held in place by a hinge pin (40), thus permitting a 180 degree rotation of the drive head. The drive head can consist of either a square drive head (30) or a ratchet drive head (31). To the second end is attached a rotatable handle (58), which allows a rotation of the wrench upon reciprocation of the handle (58). A second embodiment of the hinged socket wrench includes a second clevis (28) that is added to the second end (24) of the offset shank. The second clevis (28) functions in the same manner as described for the drive head and adds further combinations of angular displacement of the handle (58). Thus, increasing the value of the wrench as a tool and also its productiveness in difficult work areas.
