Unfortunately I ended up just drilling the screw out and retapping the hole. If you determine that your stubborn screws are really stuck I would suggest just drilling the screw out and retapping the hole. I've had bad luck with craftsman broken screw extracting sets and drill bit extractors. Drill bit extractors are made from... more info
