Powerhouse Products stud boss cutting tools include a universal arbor that also acts as a pilot/guide and fits into the original stud hole. When switching over your factory heads for screw-in studs, you need to machine down the stud boss equal to the thickness of the new stud's jam nut plus the guideplate thickness.
