I want to order some, but can't figure out the nomenclature.

They measure just a hair under 5 mm, but take a 4mm Allen key.

So I guess they're either "m4" or "m5"... but which?

M5.

You need to order screws like that where you are? There's 5 stores near
me that sell those screws, for as little as 3 cents each.

In stainless, I don't have a single source now that the good marine
fastener place closed. I order from McMaster-Carr and cut to length.
Wish that I had a screw cutter for metric stuff like the one built into
my crimping tool (nicely cuts 6-32, 8-32, 10-32 screws for electrical
work) I end up using a hacksaw and bench grinder

We more commonly add a spacer under the head than cut the
screw (chain clearance at rear carrier, etc).
