Abstract: A spanner wrench assembly including a base plate having a gripping portion extending from a handle portion and defining an arcuate cavity with an open end. At least one support plate is secured to the gripping portion and substantially matches a configuration of the arcuate cavity. The support plate is of a lesser density material than the base plate. An engagement plate substantially matches the configuration of the arcuate cavity and is secured with respect to the at least one support plate. A cover defines one elongate aperture extending to an open mouth portion formed by an adjacent end of the cover, and another elongate aperture extending to a closed mouth portion dimensioned to accept a connector head which is wider than the elongate apertures.
