    Lock-on grip bolt head stripped, now what...

    Do I have to drill them out, that will ruin the threads of the grip as well. Any tricks?

    Its not fun...Not sure of the material of your bolt...Drilling it is most likely the remedey, with an "EZ out". Hopefully
    If it the bolt is in a clamp like I have on my ODI's, ruining one clamp is not the end of the world.
    Not sure what size bolt it is, but I like to think its 4mm...Coarse most likely.

    That lists the TAP drill to tap an object with that thread. I would go smaller to be safe.
    Something like this , you need a good assortment of drills in tiny increments....

    Threads will be fine. You can get these at most hardware and autoparts stores. I would recommend the spiral rather than the straight flute.

    I have found that if I use Vice grips to compress the clamp itself it takes a lot of pressure off the bolt and I can usually get it out. If not I spin the clamp and take a hacksaw to the bolt.

    Drill Out the Screw HEAD

    Nothing but a drill bit needed here.
    No easy-out type stuff.
    With a drill bit about the size of the screw head, drill the screw HEAD.
    Stop pushing when the screw head spins with the drill bit.
    Once the screw head is removed, tension is released and the collar can be removed from the Hbar.
    The remaining threaded part of the screw is now easily removed.
    If not, it will have a perfectly centered cone from drilling the HEAD to start a much SMALLER drill bit to screw the threaded piece out. (clock-wise bit rotation turns screw out through the hole.

    Use a dremel tool to cut a screw driver slot in the bolt head.

    Yes. I had 3 stripped cleat bolts and tried drilling (couldn't find an inexpensive metal bit hard enough) and screw extractors. In desperation I pounded a cheap torx bit in there (I have a Craftsman screwdriver that takes replaceable bits), turned it and the bolts came right out. Didn't even seem to damage the torx bit either. Good stuff, craftsman.
