Wrench for use on threaded parts that are not easily accessible

A hand-operable tool for gripping polygonally shaped threaded fastener components, said tool comprised of:

• a) an elongated shank portion having first and second extremities and opposed substantially flat upper and lower faces,
• b) an open-ended box wrench head having fixed parallel jaws associated with said first extremity as a continuous integral extension of said shank portion, said jaws defining a receiving opening having parallel flat gripping surfaces angularly disposed to the axis of elongation of said shank portion and separated by a connecting surface,
• c) a first retainer plate disposed upon said box wrench head and provided with an elongated receiving slot centered above and between said gripping surfaces and having an open forward extremity and a closed proximal extremity having a semi-circular contour disposed forwardly of the underlying connecting surface,
• d) a socket wrench associated with said second extremity by way of frictionally restrained pivot means permitting movement of said socket wrench in a path normal to the plane of said shank portion, said socket wrench having an aperture containing angled recesses, and sized so as to be capable of gripping threaded fastener components of the same size as those grippable by said box wrench head, and
• e) a second retainer plate disposed upon said socket wrench upon the same face of said shank portion upon which said first retainer plate is disposed, said second retainer plate containing a circular hole in coaxial alignment with said aperture.
