how do I remove it, locked solid in hub / rotor, domed head, and already snapped 2 T25 wrenches. HELP PLS

Cut a slot in it and try removing it with a flat screw driver or impact driver?

Soak in that plus gas stuff?

Not really the same thing but last time I had a stuck thing on a bike I poured boiling water over it which made it expand enough to loosen off 🙂

had the same trouble myself after snapping 3 of the bolts off in 1 of my old hubs,,,,i was absolutely gutted when i had to fork out for a BRAND NEW SHINEY PAIR OF NEW HOPE HOOPS 😆

tis well worth paying out for new decent bolts to avoid future probs IMO

I got one out by welding an M6 nut onto the head of the torx bolt. Then use a 10mm spanner on the nut. Simples.

Try a very sharp dot punch to tap it loose with a hammer,or use a very close fitting torx female socket can sometimes work on alloy/TI bolts

hth 😉

if you have got access to a vice then clamp the bolt head tightly and then rotate the wheel (or take it to a bike shop with a packet of biscuits 😉 and use their vice)

If all the above fail's grind the top off it, remove disk and use mole grips done up as tight as humanly possible after a good plus gassing.

i had the same recently. cut a slot, no dice. seemed to be made of cheese.

start to drill it out, reversed the drill to get the bit out and it freed up the thread.

Get a punch and a hammer and give it a good dunt right in the middle. That should do the trick.

thanks all, unfortunately there`s very little head showing as in recess of hope alloy disc carrier…and its jammed in hope hoop hubs too!
looks like hot water / punch could be a good thing to do, and next time check mfrs torque settings beforehand!!!

tried punch and boiling water—-thing ain`t shifting

Stud extractor – drill a hole in the screw and thread the tool in:

Freeze spray can help.

Another trick is to tighten it up a little before undoing, or to refit all the other bolts to take the strain off it a little.

Best way to avoid this sort of problem is loctite – no need to torque to hell and back and you have a barrier to prevent corrosion.

Thanks for all advice on this; having eventually snapped tips off 5 torx sockets took along to helpful and friendly local garage and mechanic; using a T27 high quality socket a couple of good hard bangs on bolt to reset head fitting and then a proper 6" ratchet wrench and out came bolt no issues ; goes to show what a difference quality tools can make too (his T27 was about £8 for teh socket alone….)
