Abstract: A ratchet wrench comprising a generally cylindrical and flat head having an opening in its center for engaging workpieces. Interiorly of the head are two sets of cusps which are sized to receive certain cams; the inner cusps are adapted to transmit torque to a workpiece, and the outer cusps provide clearance when the wrench is being rotated in a non-driving direction. A pair of face plates are affixed respectively to opposite sides of the head so as to form front and rear face plates; the face plates are affixed to the head with mechanical fasteners that are spaced sufficiently close so that adjacent fasteners are no more than 3/4 inch apart. A plurality of work-contacting cams are mounted between the face plates and arranged to be generally co-extensive and parallel.
