A slotted head screw can be made with common tooling that many of us have.
If required, slotted is OK.

If push comes to shove, you can get copper rivets in approximately the right sizeI need a small batch of copper 145 phillips flat head machine screws with nuts.
Material:
copper 145
Phillips flat head machine screw sizes:
4-40 x 1/2"
6-32 x 1/2"
I need a minimum of 10 each.

<https://www.mcmaster.com/rivets/material~copper/> (note, alloy 110, not 145)
and cold-work the Philips indentation then maybe with a little bit of honing, a
die can cut the threads (copper is kinda... grabby, you'd want to have a zero rake
edge, like for brass).
One more idea.......
Could you use copper plated "off the shelf" hardware?
But I don't know if it could be done directly or if it would require nickel then copper plate.....

Okay, we have some pictures now
is it secret?
If conductivity is the key what about some kind of conductive coating?
