The power tool is adapted for driving one of a plurality of adjacently-spaced castellated nuts. Each castellated nut has a number of radial slots. Each nut is adapted to connect with a stud having an axial threaded bore. The power tool comprises a wrench driver for turning one of the castellated nuts. A wrench arm extends laterally from the wrench adapter. An anchor assembly is coupled to the wrench driver and includes an anchor adapter. The wrench driver has a head which carries an equal number of radial lugs for operatively engaging the slots in the nut. A retaining cylindrical skirt downwardly extends from the wrench driver's head for capturing therein a portion of the body of the castellated nut while the driver's lugs engage the nut's slots. A retaining bolt threadedly interconnects the wrench driver with the stud carrying the castellated nut prior to exerting power with the power tool, thereby preventing the lugs from disengaging from their mating slots. The construction of the anchor adapter is similar to that of the wrench driver except that the anchor socket does not contain lugs.
