Nikon meter coupling shoe screw/bolt

[Pieter12]

I recently acquired a Nikon F2S and was going over my inventory of non-AI lenses. One of the screw heads that attaches the meter coupling shoe (prong) to one of the lenses has a mostly stripped head. Any idea what the specs are for that screw and where I could get a few? Because I know if I have some on hand I will never need them.

Take it out and measure it with a caliper then order the replacements from https://www.metricscrews.us/index.php?main_page=index&cPath=98&zenid=sl7okenvonefc8mtcdli7ghlh0
Probably a M1,5 to M2.
