ABSTRACT:
A wrench provides for a movable head portion mounted pivotally onto a handle portion. The head portion includes a rod that extends into a slot in the handle portion on each side of the head portion. A blade extends from the head and is engagable within a tubular end of the handle so that the head may be positioned with the blade aligned axially with the handle in a first orientation, or at an angle to the handle in a second orientation so that the wrench may be applied to the flats of nuts which have diverse orientations when space for the positioning of the handle is limited.
