Disclosed is an integrated spindle actuator assembly for nut-runners wherein the spindle is pneumatically operated to engage and retract from the intended work device including an internal piston formed on the spindle end in conjunction with a spline which permits the spindle to translate towards the work when pressure fluid is applied to the spindle assembly. In its extended position, rotation of the spindle is possible, the spindle requiring a minimum of radial clearance, thereby permitting close spacing of the nut-runners.
