An air powered hand tool having combined therein nut running and crimping mechanism in which a common cam member is motor rotated to effect run down of a work nut about a stud and is piston driven to effect crimping of the nut in locking relation to the stud; in which an indicator visually indicates to the operator completion of the crimping action; and in which a stop prevents frictional locking of the cam member in the crimping action; and in which the stud is enabled to rise a considerable distance above the nut as the latter is run down.
