| Post subject: | Removing Sheared Off Bolt |
Hey, what can you use to get out a sheared off bolt? I have one that I broke a while ago in the back door of the Jeep (long story I'd rather not go there  ) that I remembered I need to get out. I've heard something about an "EZ-Out" or something like that. I've got the top of the bolt on my desk right now, I need to go get a new one.

What size is it? With EZ outs, you drill in the center of the bolt and use their spiral splined tool to back the bolt out....ussually work

Its all ways a tuff one but if you can get a set or just the size you'll need then the easy out will be you best bet. How it works is you'll need to drill a hole in the top of the bolt that is still in the hole, so i hope its not to small? Use a centre punch to pop a small indent so its a lot easier to keep the drill in the centre of the bolt. After you have drilled a hole say 6mm to 8mm deep (run the drill slow as bolts are normally hard) Now use the easy out to remove the broken off bolt. The way an easy out works is it has a left hand thread which is shaped like an ice scream cone, so as you turn it in anti clock wise it will screw its self into the bolt, as it goes down it will get tight and start to unscrew the broken off bolt. Its not to hard to do if the broken blot is not to small. Now i hope that made sense. But best of luck. |

Soak that sucker down with some PB blaster, Liquid Wrench or whatever you like you use. Take a small hammer and tap on the bolt and if possible the areay surrounding the bolt to help loosen things up and maybe work some of the lubricant down along the threads, go get a drink. And then come back to work on it, tap it again and then go to work with the easy outs like the others have expained. I will say this though. I have gotten many bolts out that had easy-outs broken off in them just by taking a chisel or drive and making an indentation near the edge of the bolt and tapping in the appropriate direction. Give those farmers a shocked look to see a little ball peen hammer and a chisel loosen a bolt they have broken off an easy-out trying to remove it. This can be hard with small bolts though. Just my .02 |

Worst case scenario...drill it out and tap for a larger bolt.

I use PB Blaster and Kroil (this stuff is amazing). I'm not a big fan of EZ Outs, be careful with them as they tend to break, especially if it's not centered just right. Before you try the EZ Out, try some left handed drill bits, I've had good luck with just these and some Kroil, and maybe a little heat. |

Gotta agree with welby, ez-outs are hard and break easily, thats why I got so much practice with the chisel method  And if you still cant get it out and have to go with skyjumps last resort of drilling and tapping larger, a broken off ez out is hard to drill, you will have to get a carbide bit and take your time for that situation, unless of course you have a plasma cutter on hand

In my experience, if it broke because it was overtightened, and snapped on the way in -- Yes. E-Z-Out. If it broke when you were trying to remove it because it is rusted in place, good luck using some of the penetrants and methods already suggested here. It will be common for the E-Z-Out to break also. Then you will probably be drilling it out with carbide drills and making new threads. Kroil/ PB Blaster & Never-Seez are our friends. |

Another possible solution if there is enough of the bolt still exposed is to weld a nut to the top of the broken bolt and remove it that way. A lot of the time the heat from the welding will free it up and the nut gives you something strong to grip on when removing it. |
