Abstract
A control system in an impact wrench that includes a hammer that makes an impact with an anvil to cause the rotation of an apparent operational output shaft of elasticity or to some significant analogue point by applying a torque to it, whose control system comprises: means for developing a signal representative of the deceleration of the hammer after its application with the anvil, calculating means responsive to said deceleration signal to determine the apparent limit of elasticity or some similarly significant point of the fastener assembly, and means of control that respond to said calculating means to produce a control signal when the fastener assembly is tightened to said point.
