Abstract

A torque wrench is disclosed for use in rotating a range of different sized fasteners. The torque wrench may include an input end configured to receive a torsional input, and a gear train operatively driven to rotate by the torsional input, a driver connected to the gear train and a plurality of clamps disposed at least partially inside the driver. The clamps may be movable to radially engage a range of different sized fasteners by rotation of the driver in either of a clockwise direction or a counterclockwise direction. The torque wrench may further include a housing configured to enclose the gear train, the driver, and the clamps.
