Stripped allen head Help.....

I have removed countless socket head cap screws with turned out heads in my job. The best way I found and never had fail is to use a ballbearing! First spray some penetrating oil onto the screw. Aerokroil works best. You put a ball bearing on to the socket head and whack it with a hammer. The impact tends to loosen the screw and will swage enough material back into the socket that an allen wrench will fit tightly again. Make sure you use a perfect allen wrench. If the end is boogered up use either a new one or grind the end till its good. Use plenty of water to keep the wrench cool as you grind it. If the allen wrench slips right into the socket whack it again until the allen wrench needs to be tapped with a hammer to go in. T handles or hand held impact drivers work best. Now give it a twist and the screw should turn right out. I'm serious I have done this for over 30 years and never had to drill one out.

I did the same thing last week. Took a 21/32 drill and slowly drilled the head until I could drive the bolt through with a drift punch breaking the head off. The trick was to not drill all of the way through as it is aluminum after you go through. Do not hit the drift hard, as you get closer to the screw shank it will break off with just a light hit and you won't distort anything. Took about 5 minutes. You can look at the new screws you should have bought to get an idea of how deep you need to go. The first part of drilling goes quick until you get to the bottom of the hex. Second fork came loose right away.
Good Luck

The bolt the op is referring to is on the bottom of the fork and about 1/2" - 3/4" down inside and not exposed. He couldn't hit it with a hammer if he had to. Although that is a good idea.

Got it out!
Guys thanks for all the suggestions.
I tried to use an easy out BUT it broke in there (OH NO).
So next I tried to use the impact driver with a straight screwdriver bit. The bit was a bit longer then the screw head so I tried to chisel a place for it.
I think the impact driver helped but did not get it out.
So I put my drill to it and made the allen hole a bit bigger
Then I hammered my larger tork bit in to the allen head and got my wife to hold the leg, used my 1/2" ratchet and it came loose - YES.
Thanks again!
