A ratcheting open-ended wrench includes a fixed jaw and a pivoted jaw arranged in relationship to each other to define an in-line insertion opening aligned with the operating handle portion in accordance with a conventional open-ended wrench. The fixed and pivoted jaws are formed with cooperating notched faces creating a multiple pointed configuration equivalent to a socket or closed-end wrench for mating with a hex-type head in different angular orientation. The fixed and pivoted jaw include a force transmission arm and recess such that the turning force is transmitted from the fixed jaw directly to the pivoted jaw. The pivoted jaw has a pivoted connection to one side of the handle and extends across the end of the handle and then outwardly to locate the fulcrum permitting application of closing forces in one direction and the ratcheting release on the reverse stroke.
