I accidently over-tightened the small hex bolt used to adjust the cone on my rear wheel and now cannot undo it as the Allen key keeps slipping. As the wheel set is about two years old (and Chain Reaction seem to be doing a good deal on replacements), is it worth the bother trying to rectify this and, if so, how?

Is it the thread that's stripped or the head rounded out?
 
1) The key is easily rounded - try angling it a little to get better purchase.

2) I filed down a slightly oversized hex key to undo a rounded hex nut.

3) The bolt is just a normal threaded screw with a hex slot on top which tightens the collar - so any similarly threaded screw will do the same job equally as well.

It is rounded.

I must say that any method which requires me to 'tap it', or hit it in any way, seems to suggest to me that I'd need three hands - one to hold the hammer, one to hold the driver, and one to stop the collar from shifting. Nevertheless, thanks for the ideas - I'll have another go. :okay:
