Each of the wrench sockets is provided with gear teeth integral with and extending around the periphery of the sockets. One or more gear members forming a gear train is disposed within the elongate housing and extend along the length of the wrench to provide a driving relationship between the gear teeth of the wrench sockets. One or more additional wrench members is attached to and drivingly interconnected to the first mentioned wrench to penetrate any labyrinth or tortuous path to install or remove a nut or bolt without cranking.
