anyway, id try to score the surface of the screw with something like a dremel....tho i'd make a philips scoring, not flat.. as you have a less chance of stripping it IMO, just dig as deep as you can with those scorings. dig into the metal if its not gonna hurt whatever it is you're working on too badly

Yes criss-cross with a TINY bur and you should be able to get some torque on it. Otherwise you could be screwed.
