of the times i have had trouble with allens is when i failed to clean out the socket in the top of the bolt. this prevents the allen from getting full bite and then you turn out the lands on the allen. another problem is when i have twisted the allen (allowing the shaft to be crooked in relationship to the bolt) while trying to turn.

i have a set of allen sockets for those tough ones. if you get full bite and you keep the allen straight then you should be able to twist it until it comes out. i cant remember ever breaking the head off one.

i have twisted allen wrenches, the L kind not the socket kind.

they use allens where it is tight for getting a socket in, i think.

good luck.
