Re: Need Help Quick
Hopefully, you can take a hacksaw blade and cut a notch across it... then use a straight edge screwdriver to unscrew it?
OR get a set of needle nosed vise grips and try to clamp onto it and back it out.
OR...
Next step is to visit Sears or your local hardware store and look for screw extractors. Most of them are something you drill/screw into the head - backwards - and then turn the whole thing back out. Good luck.
