the best tool i have found for getting stripped allen heads out is called
"sock-it out" they don't have a website as far as i know.  they are
available at your local machine tool provider or J&L industrial supply
which is where i bought mine.  i went and bought them after all the normal
tricks like fractional allen drivers and torx bits failed.

here is an industrial publication that talks about sock-it out and other
broken fastner removal techniques.

(gently) with a hammer. Once the Torx bit is set in the stripped-out
allen, it can be taken out just as normal. This requires no better access
to the "dead" bolt than usual, and also requires no drilling or use of
Easy-Outs. Great!
