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 180-degree drive head held by a hinge pin ( 40 ). The drive head consists of either a square drive head ( 30 ) or a ratchet drive head ( 31 ). To the second end is attached a rotatable handle ( 58 ), which rotates 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 ) adds further combinations of angular displacement of the handle ( 58 ). Thus, increasing the value of the wrench as a tool and also its productivenss in difficult work areas. Five configurations of the hinge pin ( 40 ) provide additional surface interface with both the hinge pin and the handle yoke improving the structural integrity and prolonging tool life.
