ABSTRACT:
The invention is a tool having contoured opposing jaws for fully engaging hexagonally shaped fasteners on at least four sides for any fastener within the operating range of the tool. The jaws include a two-surfaced jaw and an opposingly disposed three-surfaced jaw. The jaw surfaces are configured and positioned relative to one another in such a way as to maintain a shape which conforms to that of the fastener's hexagonal shape during adjustment.
