An extensible torque bar is provided. The torque bar comprises an elongated torque sleeve having a channel therein. A drive engagement means is provided at one end of the sleeve for engaging a drive tool, e.g. a ratchet wrench, for applying torque to the sleeve. An elongated torque rod is provided having a portion of the length of the rod adapted to slidably and nonrotatably mate within the channel of the torque sleeve. A driven engagement means is provided at one end of the rod for engaging a driven tool, e.g. a socket wrench, for applying torque to the tool. The rod has internal screw threads along the portion of its length which is adapted to slidably and nonrotatably mate within the channel. A cylindrical adjustment member, rotatably and longitudinally mounted to the sleeve, is provided having external screw threads cooperably engaging the internal screw threads on the rod. When the cylindrical adjustment member is rotated the rod extends from or retracts into the sleeve.
