Abstract: A simplified torque signalling wrench in which the torque responsive means comprises a camming recess or notch in the outer end of a wrench shank within a handle for the wrench and to which the shank is pivoted to provide limited angular movement for the outermost end of the shank with a ball surface being yieldingly forced into the recess defined by walls of the recess by spring loading to maintain the shank along the centerline of the handle and yielding to camming forces under a torque load to effect relative angular movement of the shank and handle to signal a torque load in excess of a torque load determined by the adjustable loading of the spring.
