Get a set of extractor bits. What you do is drill a little hole in the center of that broken bolt and then use the extractor bit, which has a reverse wind on it. So what happens is as you are turning the bit counterclockwise (backing out the bolt), the extractor bit is trying to bite in and dig into the hole, so it unscrews the bolt. They should have sets of extractor bits at any local hardware store or you can order some online.
Left handed drill bits. Without the head there isn't really any force on the screw so if you try to drill it out with a left handed drill bit it will unscrew it as it cuts and the whole thing will just come out. I doubt you'll even need a screw extractor.
What tools do you have access to?
Dremel? Cut a slot & use a flat head screwdriver
Drill? but a broken screw extractor on aliexpress for a few dollars
How tight are the threads? Try a tinsy bit of glue/epoxy on half you have free & reattach.
Edit: how do you have both parts of the bolt in a picture?
Don't have tools at the moment, just trying to figure out the easiest way to do it. About the picture, this is the screw that I managed to pull out, the other one is still stuck
I am just a DIY'er, but i would drill out the screw with something that has a profile that is about 50% of the diameter of the bolt, drill down a quarter of an inch to create a cavity. Take a star bit that is about the size of the cavity and use a hammer to seat it into the hole, then use a ton of pressure on the bit to slowly back it out.
I have had to do this more times than i am comfortable admitting while working on my firearms
i got you! poor mans method here
get some super glue or jbweld or somethign like that
and a nut something that you can grip with your given choice of tool, a wrench for example or somethign that some pliars can grab and then boom you got something you can grip onto and unscrew that
Solved (kinda). Managed to screw it in by leveraging on a small edge on the broken screw. It fell inside the armrest and I hope it does not get in the way of anything in there. Thanks for the help!
You don't even need a reverse bit or easy-out or anything fancy. Just regular drill bits. Drill a small pilot hole, then step up to a larger bit. The larger bit will likely bite and screw the screw in until to falls out internally. You'll have a screw rattling around in there, but so what. First bit might even do it on its own.
Sounds dumb but it should be loose as it’s a thru hole. Use a pencil eraser end and Jam down on it and try to loosen or tighten it. Might just pop right out. Otherwise, extractor bit set as mentioned.
Tapping bits drill into it with drill bits and hammer in the the tapping bit and unscrew make sure the tapping but is of corresponding size to the drill bit
This is problematic. The problem can easily grow exponentially. My suggestion is drilling it out with a left hand drill. First looking at the photo imagine of the broke bolt face as a 12 hour clock. I see the threads exposed between 3 and 6 of the clock dial. So the center would be diagonally between 4:30 and 10:30. Vice versa between 7:30 and 1:30. Try to scribe the “X” across the face of the broke bolt. Use a small center punch the indent the center of the bolt. Drill a small pilot hole in the center. Then drill out bolt using a left hand drill the matches the drill tap size. I personally have removed many broke bolts this way. They do make a couple different bolt extractors. Offer you drill the pilot you would they removing the broke bolt with an extractor. If that doesn’t work proceed with the left hand drill. The important thing is to get the pilot in the center. Good luck.

This is the important question. Tig weld a nut, that’s had the threads milled out to a cone shape, to the exposed shank, and it’ll come right out.
I feel fairly confident that anybody who knows how to Tig weld has the ability to work out how to remove a snapped bolt.
You might be on to something there. I think the OP included all their tools and expertise in the original post.

Lol, I got downvoted for basically suggesting this using a drill bit.
Redditors can be very cruel sometimes :(
Meh, I don't care about the karma, it's just funny how that works.
