Is it jammed in there?

I have removed those with pin tip in a circular motion, and with a small flat blade screwdriver tapped gently into the soft brass.  The ones I removed were the result of over tightening and snapped off remains.  The remains were not stuck in the threads.

I snapped one off doing it up too tight as it seems, I made up a small screw driver tip on the bench grinder with the tip tapered a little and quite sharp, give a couple of light but firm taps with a hammer so the tip eats into the brass, it screwed right out, just be gentle.

Just try a small flat blade electronics screwdriver. Make sure it fits into the brass part.
