Abstract
A torque wrench, basically exemplified by a torque beam having a driver at one end, a grip at its other end and apparatus associated with said driver and beam providing an observable read-out of any torque that may be developed during use of the wrench, particularly distinguished by a system for defining a prescribed torque limit in use thereof having means associated therewith for producing a highly distinctive alarm signal the nature of which is such to produce an instantaneous torque limiting response of the user at precisely that time the level of the torque applied to said beam reaches said prescribed limit. In a preferred embodiment the system for producing said signal is located in connection with a housing which is releasably based on and secured to said beam immediately of its grip, the means through which the signal is triggered is functionally related to a portion of said read-out apparatus and the alarm signal is preferably provided by a source of light and optionally by a source of sound.
