Spring back screws for Pacemaker Graphic

[anglophone1]

Shooting at the US military cemetry in Normandy last week and PING one of the two tiny screws that hold the spring back on flew off when I put in a grafmatic.
Couldn't find it anywhere so finished shoot with Hassy Xpan.
I've spent all week hunting for a replacement screw, but no luck too small and(I guess) imperial ( hard to find in metric France)
Can anyone point me in the right direction, or better yet send me one(or two looks like a spare would be useful!)
Thanks!

when I replaced mine with the package I still have for reference--these screws were labelled as

#4-40

so that's #4 size and 40 threads per inch

only metric there? too bad
