Horn Ring

I have a repo horn ring. There are three, what appear to be threaded holes in the ring so that the little items can be attached. The screws do not un-screw from the old horn ring. The old screws are hammered into (for lack of a better word) the old ring. Like a pressing. I was thinking about drilling out the holes as the local hardware dealers does not carry screws that small.

Anyone?

You might find smaller screws at an electronics store where they carry transistors and such.

CAL44, look into a company called FASTENAL.
I do not know if they are nationwide but they are rather large.
FASTENAL carries fasteners of all shapes and sizes and will most likely have something to fit your needs.
Good luck.
The original "screws" as you described them sound more like screw rivets. If you look at a screw rivet not installed it has a spiral stem and a button head. They are installed into a drilled hole and automatically "screw" into place and hold with the clamping force generated by the interference fit.
