ABSTRACT:
A ratcheting adjustable jaw wrench (20) includes a stationary jaw (36) having a window (42), a movable jaw (46), an adjustment screw (62) which engages the movable jaw (46), and a handle (22). A frame (54) is slidably disposed within the window which carries the adjustment screw. The frame is rotatably connected to the handle so that when the handle is rotated in a reverse direction (70), the frame, adjustment screw, and the movable jaw move away from the stationary jaw allowing the jaws of the wrench to open and ratchet over the flats 501 of the head of a bolt (500).
