Make sure they are very clean inside. You can't get a good bite on them if there is dirt in there, but being on top of the head they should be clean. I would recommend that you use a good grade hex socket, not an allen wrench. The socket heads I have are mounted in 3/8 drive socket and I would recommend using an adapter to go to 1/2 drive. Get that hex head into that screw real good and give it a good pull with a half inch ratchet or breaker bar and it will move and it will not break or strip.
