Snapped a Bolt! Help!

Well I am really embarrassed about this because I usually don't over tighten bolts but for some reason I did. So when installing my lift a couple days ago, I was tightening the bump stop extension bolt with a torque wrench (following the directions). I felt that it was tight enough but I kept going and sure enough it snapped. Today thinking that I could fix it, bought some screw extractors, drilled a hole in the broken bolt and ended up snapping the screw extractor inside the bolt. PLEASE any advice is appreciated. I really need some help with this. Thanks in advance.

Can you turn that nub with some Vicegrips? Weld a nut on the end?

I've tried turning the other end with vicegrips but no luck. I don't own a welder but if thats last resort, I could search around to find someone that has one.

Depends what the extractor was made of

If it is carbide only option to get it out of hole is a punch and hammer and shatter it

If it is tool steel can drill it out with a carbide bit

Next time you have a broken bolt try a left hand drill

Always make sure you drill dead center as if extractor hole is off center and gets into threads it won't extract

Slow and correct is faster then quick and dirty

I'd take it to a welder to have a nut welded onto the bolt from the inside of the nut. Anytime I've done that, the heat from the welding did as much to getting the broken off bolt loose enough to unscrew as the nut did.

Thanks for the advice. The extractor is steel but it broke off unevenly and is hard to get a drill bit centered.

Would it be hard to weld a nut on that short of a nub on the end of it. and if I were to take it to a welder, where should I go?

Welding a Nut on it is going to be Your best shot at this Point you are not going to be able to drill into any good ez out (Hardnend Steel)

Most any welder could easily do that job. I'm a hack welder at best and have done that job many times and each one was successful at extracting the broken or seized bolt.

Thanks guys for the advice. I really appreciate it. Welding seems like the best option right now. So on that point, should I look for a business to do it or some kind of fabricator/local guy.

Like indicated above, look for someone to come to you. Craigslist may have moble welders or i just googled and there are moble welding services by you. The issue is if you take it some where, they will charge you for disassembly and that will be a couple hrs of labor (at around $100 per hr)

2 suggestions both of which I have done.

1. I had this happen to me before on one of my audis, if it is a good grade bolt you can cut a slit in the top portion you can see with a dremel cutoff wheel deep enout to get a flathead it there and back the screw out.

2. find a nut that you can thread onto the top, with it off put some JB weld epoxy onto the the nuts thread and screw it on, wait for it to set and you should be able to use a socket to get it out.

Worth a shot and even if it was too tight you will still have enough metal there to weld a nut onto it plus you wont have to wait to find a welder.

Best of Luck!

Use a small drill bit and drill up the side of it all the way through, do that on two sides and take an air chisel (punch style) or a punch style chisel and a hammer and hammer it out. You'll collapse the bolt on itself.

Then you'll likely need to use a bigger bolt with a nut on top and use a wrench up top to hold the nut in place while you tighten the bolt.

Use a torque wrench...saves you the hassel of having these problems. Been there and done this in my early days of wrenching...it isn't fun, I feel your pain.

Isn't this why we did "tap and die" in shop class? Could you create a new set of threads and screw something into the middle of it then unscrew that, just thinking, I think that was 7th grade so forgive my crazy ideas ...

He has the Easy out stuck in the middle now.

Also, in order for that to work, you'd have to put left handed threads in so that when you tighten the new bolt down you are losening the stuck one :P

Well its all fixed now. Ended up just drilling straight through the stuck bolt and put a new bolt through with a washer and nut at the end. Thanks to everyone for the help and advice.
