Does anyone know how to remove these screws?

Question

Iron

Their head is specially licked in the direction of unscrewing.
There is no Dremel, and you can’t crawl, it’s too deep.

Answer 1

As a result, I came to an extraordinary solution.
I bought a small drill, 1.2 mm. Drilled screws on the sides. I made a U-shaped bracket and carefully unscrewed the screws with it.

Answer 2

Answer: "special key" will help?

Answer 3

It's not really clear from the photo, but it looks like screws that can only be tightened. In this case, I would suggest carefully drilling out and then replacing with ordinary ones.

Answer 4

You can try gluing a screwdriver to a self-tapping screw with instant glue. True, without guarantees, I have not tried it with such a slot, and I don’t know how to wash it off from a screwdriver later.

Answer 5

So?
