An easy-out (or "screw extractor") is a special tool to be exact used to remove stripped bolts or screws. It looks kind of resembling a drill bit with the spiral going the wrong way. It will come next to a drill bit of the correct size for use with that easy-out. You need to buy the right size easy-out for your bolt, so weigh up the head of the bolt and try to match it up within the bolt section at your hardware store. Then go over to the tool article and ask the clerk for that size easy-out. When you get home, chuck the drill bit in your drill and drill a hole into the center of the bolt. Try to label sure that the hole goes straight into the center of the bolt so that you don't damage any threads of the metal within the original part. After you go and get the hole drilled, push the easy-out into the hole and turn it counterclockwise with a wrench. The backwards flutes on the easy-out will lock into the hole in the bolt and verbs the bolt out. After you get the bolt out, you can chuck the bolt a vise and twist the easy-out clockwise to free it so you can use it again following. Good luck. All the above are good answers unless it has not here handed threads!
Put some penetrating grease on it and let is set for awhile, if the threads are rusted this will help break through the rust or corrosion.
If it is not recessed try using vice grip pliers. You may also try turning clockwise 1st.
You say that the screw you own a problem with has a commander that was designed for a certain size allen wrench to be used contained by the installation and removal of the screw; and that the hex shaped HOLE in the screw head have been damaged (rounded out, I run it) so that the proper allen wrench can't get a proper grip to unscrew said screw. Sometimes you can use phillips head screwdriver that is to say just about equal size as the allen head opening to stroke it down tight enough into the ruined hex opening to take a good enough "grip" to vertebrae the screw out (if the screw CAN be backed out.

Your next hope would be the easy-out as have been suggested. Your hardware store clerk will know what you're asking for. You'll need to know the approx. size of the allen director opening. The easy-out has adjectives threads on the pointed end that are designed to bite into the steel of the damaged screw commander by turning in the direction OPPOSITE to the direction that was needed to insert the screw into its socket. When the easy-out bottoms within the damaged screw head it will put a positive HARD twisting dealing on the screw to back it out (if it's not frozen solid by rust) -- then, it'll break. Maybe that's why the allen wrench messed up the allen socket surrounded by the screw head in the first place. UGH!

Wishing you Good Luck!
It is a device that, when you attach it to your electric drill, will get out any stripped screw. Follow the directions on the package for best results. EZ-out is also agreed as a screw extractor if you're going to a hardware store.
You may be capable of use a new allen wrench to remove the screw. Or grind away the end of tattered allen wrench. I have done this many,copious times. go to auto supply store and get a LEFT HANDED drill bit the size of your unusable Allen wrench .. put it within a drill putting drill in reverse ... when it gets a apt bite it will screw it out for ya[ operate drill on slowest speed]
Answers:    An EZ-out looks like a screw with coarse threads that are left-handed, and have a square shank that you can grip with an adjustable wrench. You buy a small set of these, 6 or so, for different sizes.

You simply push the point against the stump and turn counter-clockwise. The spiral edges cut into the metal enough to grip it. Take it slow and graceful. If the Allen wrench was small, e.g. for a set screw, you may not be able to find an EZ-out that fits. In that bag you have to drill it out and re-thread the hole for a slightly larger size.

Good luck.
When screws get F'Uped. Take a hack saw (if you don't own one you should, buy one beside a metal cutting blade,) and carefully and slowly cut a grove across the screw pave the way. Not the best solution in many cases but within time you will make a flat head screw. After the grove is wide enough and wide satisfactory use a flat screw driver to put it in place.
