ABSTRACT:
An open-ended wrench is provided in which the jaw and handle are formed as a unitary member with the jaw being offset with respect to the handle. A plurality of shims are longitudinally slidable from a location outside of the jaw to a location inside of the jaw to vary the dimension of the nut-receiving opening defined by the jaw. Interlocking means are provided to prevent one or more of the shims from being located inside the jaw opening unless there is supportive contact with the jaw.
