    What is your plan after you remove the bolts? I would respectfully suggest that you have stripped the threads in the stem, not the bolts, especially if it is an alloy stem.

    You'll need to think about redrilling and retapping for a larger bolt... and whether that will work.

    And it might be worth remembering not to reef down hard on nuts and bolts on bicycles.

    Just to clarify, can you define "stripped"? For example, are the threads stripped or is the tool interface all jacked-up?

    This is how BMXers get a bad name

    All i've ever done to get a stripped allen head out, is use a torx bit.

    Ahhh. In that case, WTP's suggestion, or a pair of multi-grips and if that fails, file two flats on the bolt edges opposite each other and use a shifting spanner/crescent wrench or the multigrips again.

    Before doing anything else, buy a brand new allen wrench that's the correct size to fit your bolts and try using that. You will be surprised at how often that will work. If that does the trick, remind yourself what happens when you use a worn tool or the wrong tool for the job. Welcome to the school of hard knocks.

    If that doesn't work it gets progressively more complicated. The next easiest plan is to use a Dremel to cut a slot in the screws and use a big bladed screwdriver to remove them. The next plan is to buy the right size EZ-Out and the right size drill bit to go with it.

    Good luck.

    And if you have any JB weld, use that and glue a allen key into it.
