Abstract: A multi-mode wrench comprised of a drive head and a housing in which a drive system is positioned together with an axially and rotatably movable handle for selecting among various operating modes offered by that drive system. The wrench, accordingly, provides for a wide variety of bolt or nut tightening or loosening operations, making such work in especially tight or confined areas easier where it might not otherwise be possible to move wrenches in a normal oscillating fashion to apply torque to adequately tighten or loosen a connection.
