1. Vise grips. That might work with a socket-head cap screw, but is out for pan-head fasteners.
2. Grabit screw extractor (drill on the right end, extractor on the left). They take less drilling than conventional fluted or spiral extractors, and are much less likely to break
3. Left-handed drill bit to remove the head. Hopefully it will spin-out. Fall back to a smaller bit and screw extractor if it does not.
