hi my fellow rotary heads, i was going to do rear brakes on my car and removed 7 lug bolts. on my 8th one the cap on the stud broke off and rounded the splines on the stud, ive went trough about 4 caps(good) tryin to get it off, ive converted all other lug bolts tfrom two piece to one pice to prevent this from happening again. has this happened to anyone before, and if it has can i get some advice or ideas on taking it off? thanks jose

 

My dad made a tool for us to use when this happens, and it was the only way I got one off.

 

hammer a smaller socket on and let it rip

 

do u have a pic of the tool?, i tried that with the socket and it rounded the splines, wat size did u use? a13mm is wat i used, was urs a six point socket or a twelve point socket?this is really pissin me off because i got to get it off, because my pads are about 1mm away from being metal to metal, and then screw up my rotors. the last thing i need is to turn a 30 dollar job into a 100 dollar job. anyways, thanks again.

 

craftsman makes some good bolt/stud extractors. they are like ez-outs, but go around the outside of whatever is stuck. between those and PB Blaster, i've never had a bolt i couldnt remove. i'd be lost without them!

this is the set i have. tools of the gods!

 

wow, thanks man, im goin to sears as soon as i get offline

 

bolt out works wonders, a big seller at our store.

 

I will get a pic in the next few days, You would need a well stocked garage to make it though. I have been meaning to ask Billy to make me a few more of them.

 

well, i tried the bolt out crafstmen set and none of them worked. i was out for about 1 hour tryin it and it just kept roundin the plines up, its really tight. Hades12 if u could get that pic that would be nice does anyone have any other ideas?

 

well if i understand what u mean correclty..as in ur stripped the bolt...id take it to a shop..or if u have a welder and weld on a nut and then unbolt it...thats what my friends dad does when he need to do someones brakes an they dont leave him the key for the lock

 

hmm, thats pretty good, get a nut thats a little bigger than the stud, weld it on and zip it off, i like that 83rx7boy. good idea.

 

^^^ yea im pretty good for a 14 year old

 

lol, thanks for the info, too bad its sunday and **** aint open, cuz i dont have a mig welder, o well ill wait till tomorow. thanks again.

 

well i would use a lot of pb blaster and then if you have a file just file the stud down to a hex head so you can just put normal socket on it

 

thats a good idea too, i guess ill do this before i mig weld, then the mig welding will bemy last resort. thanks

 

P B Blaster and heat to break the corrosion bond. The heat will do more than anything else you can use, without tearing up the bolt to the point that there is nothing left to grab. Welding a nut on it will have the same effect.

Old shop trick for removing studs from cast iron exhaust manifolds is to use an acetylene torch, heat the stud cherry red, stick a lump of beeswax on the stud to cool it, then immediately use the bolt out. The idea is the heat breaks the bond, the beeswax quenches and pulls the heat from the stud, shrinking it, while the manifold is still hot and expanded.

 

if all else fails, you could drill it out to tap-drill size and run a tap through it. has to be dead nuts on center though.
