Cup Packed FF200
Helicoil is the word you're looking for
Agreed.
A lot of people have never heard of these, mainly used in engineering (which is where I learned how to use them).
Search the net to find out how to do it (save me sriting a guide, I did write one for the 106rallye register but I can't find it now)
The helicoils thenselves are pennies, the kits with the die/taps obviously cost more.
Its pretty tricky (especially the drilling) but 100% effective, a lot of the time the actual helicoil is stronger than the original material (ie alluminium) so they are 100% perfect for almost any repairs (I know people who have used them on things from factory assembling machiney to spark plug threads).

When used in factories for maintenance and repair etc they are used on machines with far greater forces than on cars. - Trust me.
Just search the net, your'll be suprised how they are often stronger than the original thread.

was mainly thinking of the fact that, for an application like this, it'd have to be put in *dead* straight and the chances of you managing that (by anything other than luck - and whilst the hub is still on the car) is slim and not worth chancing (IMO)
besides, should hopefully be able to get the snapped stud out

I agree, try a stud extractor first (if you want to) as theres nothing to lose, but damage the thread on the hub in anyway and your'll be at the helicoil stage anyway - as trust me, you dont want to risk putting road wheel bolts back in to damaged thread on the hub.
It also depends on how much of the stud is available and 'sticking out' or available to get at, if you like.

good point, unless its seized solid, ie rusted (corroded) in.

why don't you complain to whoever fitted the wheels, as you said you had them fitted !! so you obviosuly didnt' do it yourself, and don't know how to change wheels yourself, so best just drive around to lots of small garages and ask them to remove it as you won't be skilled enough to remove the bolt yourself. and it would cost you about £10 instead of buying other crap

thanks for all the replys, im quite confused now. ive never heard of helicoil's?!
a mate of mine thinks we can just heat it up and pull it out with some mole grips. its in the front hub by they way. i can still see the bolt but it just looks like the head has snapped off leaving the threaded end inside. do you think is hould just take it to a garage and let them get it out and put the new bolt on for me?

got one out of a valver years ago by getting some grips on the back of the thread where it sticks through and just turning it out, wasn't that tight either really

my cup sat a spark plug about a year back. had it helicoiled. engine stripped and checked, put back together. happy days since
if it's not too far in, try that (knocking it round)
then, once you've got a couple of mm proud of the disc, either have a go with mole grips/pliers or (if it's still tight and that doesn't work) cut a slot in it with a hacksaw (wheel bolts are high tensile steel - should still be possible though) and use a screw driver to unscrew it
edit - just read that you've (may be) got something proud of the disc: hacksaw and screwdriver

wouldn't be able to take the disc off if the bolt is through it, into the drive flange

why not if it's snapped? Disc will slide straight off

i will sell you a replacement hub for 30 delivered.
a burnt one
Whatever you do dont heat it up, you're mate is a numpty for that idea, it will only expand the metal thus making it impossible to screw out.
Drill it out is the easist option, as has been said, if the bolt head is not there there is nothing holding it in other than the thread, get a decent centre punch, drill it thru' then get a left hand drill a ball hair bigger than the right hand one you drilled it through with and Bobs youre auntie!! Just drill it slowly and you'll be ok.
Will be easier than putting a helicoil in as i doubt youll have the proper sized drill, tap (a metric one) helicoil kit, tang breaker etc etc, also to helicoil it will still require the original bolt to be drilled out, provided you dont damage the thread on the way out then you wont need to have a Helicoil put in.
