I'm assuming the hex head is stripped and not the screw hole.
If it's just rounded out and the next allen key size up is too big, try a different shaped bit (i.e. torx or square). If you're using imperial keys, try metric, or vice versa. I picked up a nice "micro" bit set that have tapered bits, useful for getting mangled screws out. It's a little set that has hex, torx, and other assorted one.
If you get a bit that is a tight fit, give it a little tap with hammer (or heavy-ish wrench) to set the bit in the stripped out screw head. Then while applying downward pressure to keep the bit solidly in the screw head, slowly rotate the screw out.
If you can get a really fine triangle shaped file (almost like a jewelers file), you might be able to get a grip on/in the screw head. The triangle profile seems to be just right for getting a stripped hex head out, and a file is really hard and will "bite" into the screw metal.
If it's loc-tited in place, try heating it for a bit with a lighter (don't have anything that will melt/burn touching that part) to soften the "glue". Or a soldering iron. Don't heat the screw directly, heat the surrounding metal.
Good luck!
