pinch me!

just fitted a mates rear wheel to his bike and could tell by the way previous owner had done a few things something was going to become a problem.and i wasn't long.
went to remove front wheel.....and one of the front axle pinch bolts was rounded off to a near perfect circle!
no chance of getting loose, feels like they've been done to 100nm!

any ideas / solutions to how i/we would go about getting this monstrosity out?

Thanks

 

thanks martin.......forgot to mention that its an allen key pinch bolt

 

I must be having a blond moment Martin, can you explain the lacky band trick to me in smaller syllables please. I can’t get my head round what you mean or how it would work.

 

Is it a button headed allen bolt or a socket cap?

For a socket cap you could try some mole grips.
Or could you carefully dremel in a slot and then use a flat blade screwdriver?

 

As above a torx bit should see it out.

 

i guess neither as the whole head of it sinks in flush with the forks so nothing else will grip it will try elastic band trick on it see if that works

 

I use a torx bit tapped in with a hammer then a quick hit
with an impact driver takes it straight out.

 

violence is the answer........ torx bit and hammer as the many have said

 

Much as I like this one, you can also get a set of easy outs (They're basically a hardened screw with LH thread. You drill a small hole in the bolt and then screw the easy out into it. Because it's LH thread, it's torquing the bolt in the direction of loosening... Eventually the torque of putting the easy out in, undoes the bolt.

Here's a set on flea bay.

Bet you the threads in the fork bottoms are fucked too.

Why do people think pinch bolts are required to be really tight? The clue's in the title......

 

Thanks Martin, I get it now, told you I was having a blond momemt.

 

As said size bigger torq bit tap him in should fly out or if you decent with a tapper tiny chisel mark it and tap away watch the forks though

 

theres no reason they should be fucked.

as others state,torx head or cut a slot and use a falt head screw driver.

 

Thanks for all advice people
Will hopefully get round to trying today and will let you know the out come

Does annoy me like others have said there's no reason to be done up so tight .
There's another one to try and get out as well which isn't rounded but boy does it feel fucking tight
GRRRRRRRRR!

Helps to ease the pain knowing its not my bike but still…

 

give it a good soak with wd40 first aswell
