Getting a headless screw out

Found out one of the screws' heads snapped off where you would mount the side mirror mounts for the body. How can I get this out without damaging the thread on the body? I was thinking about drilling out the screw. Take a large drill bit, drill inside the screw so it would be so weak, I could snap it like a stick. I did drill it enough to put one of those inside screw grippers but the gripper didn't grip it well enough.





I did not notice this till today. Kinda hard too when you have a black jeep and it's always dirty XD

Had a head bolt break off in my block before. Not to long ago actually. Try taking a drill bit and drill through the center of the bolt. This will release some tension on the threading. After that you may be able to reverse it out with the bit but if not try the easy out and reverse it out. Should work. Last option is to take a left handed bit and see if that sucker will get it. It may take some time but make sure you drill through the bolt straight in the center where it will release the tension of the threads evenly. Hope this helped! Good Luck!

Mine did the same thing, they were torx bolts on my jeep. I went in with my tig welder and dabbed the threads with some wire for buildup, then grabbed them with small vice grips and they backed right out. Do you know anyone that specializes in welding? They can help you. I am a welder for a living but I am pretty far away from you.

Take a unibit and drill off the top of the bolt, remove the bracket and use a needle nose vice grip to twist the bolt out. I did all 10 of mjne that way

EZ-Outs, LH drill bits, etc. are a waste of time for that kind of broken bolt. The above suggested welding technique works primarily due to the intense heat it generates at the threads. Many times I would have a seized bolt with a snapped or stripped bolt head. The snapped off or stripped bolt would defy all attempts to unscrew it. After welding a nut or bolt on top, it would then unscrew with little or no force. The heat from welding alone loosened it dramatically... enough that a wrench was barely needed to remove the damaged/seized bolt.
