I use a hex removal tool (kinda like a screw extractor only made for hex heads) It has a tapered hex on the end. A slight tap with a hammer, put a wrench on it and out it comes. It's a kit with 4-5 different sizes. I believe that I got it from ACE or OSH. If you can't get a dremel on it then use a punch and hammer. That will flatten the top out a little ( usually enough to get the allen to fit tight again. The punch method works best on flathead screws but will also work on any other type of screw you might use.
