Simply install it in your impact gun using low air pressure. Shake-N-Break is an air impact screw and fastener removal tool that uses standard, changeable, 5/16-inch hex insert bits that fit any or all fasteners and screws. The tool will loosen rusted, corroded, undercoated, painted, dirty, and overly tightened screws fast and efficiently.
