removing rounded bolts

[stevo]

anyone got any tips? its actually on my escort and i need it off to replace the brake disc. its a 13mm head and ive tried a 1/2" and even hammered on a 12mm socket with no luck

Tbh m8.. apart from that and caking it with WD40 before hand is grinding it off? you got enough room there to cut it off

If you can heat the area around the bolt with a blow torch or gas welding torch you should be able to loosen it .
That is if the 1/2" socket stays on.
Another trick i to weld another short bolt to the head of the other and use that to undo it. The heat from welding often helps too.

have you got they crappy 11 point or the 6 point hex shape sockets.hammer on a hex bolt shape socket.

theres not really enough space to get a grinder in and i haven't got access to a welding plant at the house, those extractor jobbies look like the way forward, thanks for the fast replies fella's

Buy a BMW never happens on those failing that if you can get in there with a drill (and good quality tungsten Carbide bits) drill into the bolt end (not the nut end ) start with a small bit to get centred, then once you have drilled a small pilot hole drill in there with the bigger bit until you drill through the bolt head and into the shaft of the bolt. chisel the remainder off and bobs yer uncle.

As much of a fan as I am, I wouldn't have a set of extractors if that were true!

ok then buy a BMW and move to a country with 1 day rain a year, never happens on those


sadly i also know good techniques for removing stubborn bolts all too well from my UK garage days, bloody damp cold dark places they were!!!

yeah yeah, rub it in

theres no nut on it, its one of the bolts that hold the caliper on, kind of round the back in the wheel arch, if you know what i mean

[mrLEE30]

rub it in??? mate its 54 degrees here today!!!! if we go outside we melt!!! but we dont get rust!!

as for your problem either the above suggestions ie your extractors or plenty of WD40 and get i there with a hammer and chisel, watch yer thumbs

good luck

Often just putting a little tightening up pressure breaks the seal, try using a small cold chisel, hitting the bolt head sideways to tighten and then to undo it.
