rounded alan key bolt on coilover collar.. ideas please



  Ph1 T
Was having a look at suspension erlier and was going to lower it 5-10mm managed to do one side but came to the other and the alan key bolt head has slightly rounded off so the alan key wont grab correctly.

ive read about a few methods, hammer a slightly bigger torx bit in till it grips then try that,, also screw extractors cant really see them working though.

anyone got any ideas? surely this has happened to someone else?

dont want to have to drill it out if i can help it

Help appreciated guys..

Before you do anything, soak it in penetrating fluid and leave it overnight.

cheers will this fluid just make it easier to unscrew once left to soak in, never heard of it tbh will your average DIY store sell it, B&Q Wickes ect..

Wd40.

It will give you a better starting point. There is no point hammering a torx bit in there if the bolt is siezed as it will either chew the torx bit or the bolt.

If that doesn't work, get a bit of heat in it.

As Dan and James have said, heat is a wonder for getting bolts out.

Find out what bolt it is and get a replacement ordered too, as when its out you dont want to be refitting it!

Take the car to your local garage/tyre fitter and get them to buzz gun the strut top off and then slightly tighten up to get you home.

No mate, the only time I've fucked a torx bolt up I had to go to my uncles so he could weld me a nut on top :(

I had similar problem with my motorbike calliper. Tried everything mentioned above in the end I got an old work mate of mine who is a top engineer.

What he done was drill a pilot hole with some kind of stubby drill bit to get started bang centre. He then used a normal drill bit that was a bit smaller than the bolt drilled into it and tapped the outer threads in so they collapsed inwards with with a punch.

We were very lucky and it came out. That is your last option I am afraid like it was my last option before I bought a new calliper , f**king hate these sorts of allen key and torx the just round and shear happens all the time.
 
Just do the larger torx bit thing, and heat the area up. This will cause the metal to expand and you should be able to undo it.
It really does work. I'd never used heat on anything before, then I had a seized spacer, and worked wonders.
So yea, I'd heat up the collar/bolt/area around it, and smash a larger torx bolt into it, and then try loosening it.

will give it a go mate have to get a blowtorch this weekend :) praying it works cba to drill it out
 
Providing you manage to get the larger torx bit in properly securely enough, and it bites properly and doesn't slip. No reason why it shouldn't with my method.
I would also spray some WD40/Penetrating lubricant on it a few days before too.

I bought a Blowtorch from homebase the other day. If you were closer I would've lent you it!

not too sure what sort of access to said bolt you have but, when I rounded one of my torx bolts, I found using a hacksaw, cutting a - along it and using a flathead screwdriver worked wonders, still using that bolt to this day!
