    stripped allen head

    96 R1100RT
    While trying to remove one of the two allen head bolt holding on my rear brake rotor, after heating extensively with heat gun, propane torch and acetylene torch and still not being able to remove the bolt the allen head stripped . the other side came out with no heat at all? So now I have to drill it out or leave the same rotor on the bike. It looks like the 4 bolts that hold the wheel on would keep the rotor in place without any bolts. Anyone have any ideas? Thanks Woody

    Always easier with a picture but I will have to guess the part where the Allen head fits into stripped out? I frequently drop a nut over it and weld in the center so I can grab it again. I have also chiseled them around in a circular pattern but that's a bit iffy.

    take a next sized up torx bit and use a hammer to drive it in and form a new socket. This has never failed me.

    Do this and try no heat. Any low level thread locker was cooked with all that heating you did before, now you are just expanding the fastener.

    Yep, great advice.

    Any/all of the comments give you a simple solution.

    Don't know if this is applicable but it is not uncommon for a weldor to place a hex nut over a stuck fastener and plug weld it on. In addition to having a nice new hex head the heat also helps. In not as good of a welder as some so I weld a heavy flat washer on first then a nut.

    Good luck
