low torque spec

As I recall the maximum torque specification for the cassette positioning bolts is only about 10 ft-lbs and they require a T-30 Torx bit. The lower right one is identified by the orange arrow in the photo below.

Maybe someone used a Phillips screwdriver or an Allen wrench on them. Or more likely, tightened it with an electric or pneumatic tool with no consideration for the torque spec and stripped it. Anyway, have you tried seating the Torx bit into the bottom of the bolt head opening by tapping it with a hammer? Then press on it hard with a socket drive and rotate. Or better yet use a small impact driver. It should not take much to break it loose. Fortunately, the large diameter shaft of the bolt is fairly deep (black arrow in photo below) so if you have to drill it you should not break thru to the other side adding metal shavings to your troubles.

another option would be to drive a allen head or a larger torx bit in there and make it work... a T35 might work or a twelve point socket might do the trick. dorman help products does not carry a replacement but i have a core motor of these i can pull and mail to you if you need it bad.. would be glad to help for free if you need it.

Make a nick in the circumference of the bolt with a cold chisel then drift the bolt around with a suitable weapon, probably the same cold chisel.

Or, cut a slot in the head using a cold chisel then use a flat screwdriver.

i'd try cutting a slot in the head with a dremel tool or die-grinder and use an impact wrench (the kind you smack with a hammer) to get them out. you could also try using just the tip of the impact wrench on a pnuematic impact wrench (mine pulls off and takes a 3/8's ratchet). that way you could push hard and let the impact wrench do the work. they should come out pretty easily.

This is what I do whenever I strip a bolt or nut. Except I use a sawsall...lol
