Yes hence why it’s getting smoothed and filled and painted
Didn't catch that. Whatever works. I wouldn't, but its not mine. :) If its getting filled and painted, I would at least try the slot trick.

Dremel is the last tool to reach for in the tool box. The absolute last tool! Could I say it another way? The absolute last tool. As in "Never use that tool"

Rotary tools have their uses, but I agree this is absolutely not the place for it.

I’ve already created some extra work. If it wasn’t a self tapper I might give this a try but it’s likely just cross threaded into the metal

I totally get it, especially if its cross threaded.

It's raised enough that you might be able to take a small Dremel cutting wheel and notch a slot into the top of it to allow a screwdriver to back it out.
Great idea. Use a tungsten carbide dremel bit.

I would begin with a small drill and drill it out - increasing the drill size each time - go slow and eventually you will get it to break apart. Then you have the choice to tap properly or drill it out and put in a Rosen or Keensert -

I’d love to. Tried that. But then went to an extractor bit that broke off. I can’t drill through it now

Well it’s a bummer but…let’s be honest. If you hadnt posted here, no one anywhere would ever even know about it. Those are the best kind of mistakes. 👍🏻
