They are ALL like that and you can easily make a tool to remove them. I did it in my leeetle hobby mill. All it takes is 2 ½x3 pieces of material, I used brass because I have it.

Hold it together with superglue, drill 3 holes off center on both axises, tap the 2 outer holes on one piece, the center hole on the other piece. I used ¼20 because I had bolts long enough, make the opposed outer holes clearance for the screws, the center hole in the other piece ½".

If this isn't clear, one piece will be 3 holes from right to left, ¼20, ½" through, ¼20.
The other piece will be Clearance, ¼20, Clearance.

Now, clamp the Hinge top with the ½ hole on the head of the pin, clamp the bottom piece on with the center ¼20 on the bottom of the hinge, now, you will have to grind the tip of the pin screw, (center ¼20 screw) to make it under I think 7/32 because that is the hinge pin size, and just thread it up from the bottom, this WILL break it loose.

Imagine a chain breaker.

Ps. I used Allen head cap screws because they cleared the body
