ABSTRACT:
A power operated wrench having a clutch means disposed to effect relative rotation between the drive means and the output spindle. The clutch means cooperates with the gear reduction system to allow the drive means to continue rotating thereby allowing repeated application of the maximum torque output of the drive means. The clutch means further effects a reduction of the system inertia which must be absorbed by a fastener after high speed run down and thereby prevents overtorque.
