Abstract:

A wrench possessing a body situated at the juncture of two perpendicularly disposed handles each extending along a longitudinal axis lying within a fiducial plane is given. The body possesses a plurality of open cavities, each presenting a hexagonal aperture normal a central axis. Two blind cavities have central axes within the fiducial plane, opening opposite the handle side. One cavity is through the body, with a central axis normal the fiducial plane, has stepped walls and presents two opposed hexagonal apertures. Each aperture is of a different size. Each handle has one free end of hexagonal cross section normal the longitudinal axis of that handle. The two ends are of different size. A plurality of hexagonal engagements, both male and female, each affording full perimeter contact with a workpiece is thus enabled by a single tool.
