I know this is pretty basic but might be helpful to someone.

I'm not big on drilling out the remains of a bolt after the head breaks off, most times you end up drilling into the threads resulting in having to drill to the next bolt size and taping new threads.

I prefer to weld a nut on the stud, apply some heat, it always comes right out. :chili:


So today I tacle some bolts I broke of when I was trying to remove the brackets to my rear bench seat.

Lucky for me the bolt extended right through the floor and I was able to thread on a nut, if there wasnt any stud I would have welded trough the center of the nut and down into the stud.

Mig weld the nut.

Many times just the heat from the weld will loosen up the stud, this wasn't the case for me so I got the torches out and heated up the mount, and they threaded right out.

I did three of these little buggers

Nice.. do you know if anyone has used that "glue" that everyone seems to be trying for body work.. I think 6L used it to secure his rear quarters on...instead of welding.

I am still not convinced I should sink the $$ into a welder.

I welded my panels on, and if I was to do it again I would glue it.

I glued my rear quarters on with JB Weld and it has held up fine. I used 6 pop rivets to help hold the panel in place while it was drying. The panels have been glued on now for 3 years and have held up even with light wheeling and driving over 80mph.

Looks good, bossind. I have 5 of those bolts to get out still. I'm hoping there's enough thread to get two nuts on, so I can jam them together (like taking out exhaust studs on a bike). I don't have a welder yet.

i broke the same bolt and just had to leave it (before i got a welder) might have to go try this.

I know this is an old thread, but I have these same bolts stuck in my bed, and I need to get them out, the easy out isn't working and I don't know if these things are hardened b/c they are eating up my drill bits. My question for Bossind is... and this might sound dumb, when you applied heat, did you do it from the underside? how hot (bright) did the mount get? do you let it cool off before putting a wrench on it?

I tried heating one up with a torch and my buddy cooled it off with some water, I think blacksmith's call it quenching, anyway I think it hardened the bolt, I was trying to get it off with some vise grips immediately after it started glowing orange...could that have been a mistake? I am going to weld some nuts on 'em like you say, and try it your way, cause I am out of sharp bits. Oh yeah if this works I'll be that "someone" you help out.

You want to heat the nut that the bolt/stud broke off in. The idea is to expand the nut and not the broken off bolt. The original nut should be on the bottom side so that is where you want to put the heat at. Get it red hot, and usually it doesn't take that much, and the broken off bolt will come right out. Also don't forget to peel back the carpet on the inside or you might have another problem on your hands.

 

[mickaila]

liquid wrench it too.

 

[DaveGibson1989]

Yea, well I got tired of the bolts and moved on to the 11 spot welds on each side, I have one plate off and am going to cut the nuts off (never thought I'd need to type that, LOL), and then weld on some replacements and put the darn thing back and weld it back up...its all good though I need the practice anyways. thanks for the advice though.

Tried this twice and the bolt just broke smaller and smaller so i had to drill and rethread.

another thing u can do. is heat the bolt and put a candel on the bolt the heat sucks the wax in the treads let it cool and most times u can turn it with your hands.

That's a new one for me. Thanks

that really works? wow!opc1:

 

[chicho]

would the candle thing really work?opc1:

when i first heard about i didnt think it would work. but after i tryed i was very happy to find it does. now ive only done it like 3 times (manifold bolds) maybe i got lucky but ive nevr had a broken bolt come out that eazy after trying it. now if the bolt is broke off flush i dont think it would work.

I've done it plenty with the bolt broken flush, have to remember mig won't stick to cast, so its not a problem.

bossind i was talking about the candle trick. but i have welded many nuts to get bolts out. and it works good

Had no idea, as you replied to the tread on welding a nut on to the stud. Should have quoted the candle post.
