Abstract

An electronic torque wrench has a lever arm pivotally coupled to ahead member which is adapted for coupling to an associated fastener for rotation therewith about the rotational axis thereof, a torque sensing device being disposed on the head member for movement therewith relative to the lever arm. Different embodiments are provided for different degrees of relative angular movement between the head member and the lever arm.
