This horn plays better than my Yamaha YCL221 ever did, in my opinion, but there is one issue I keep having. I'm not good with instrument jargon, but I'll do my best.
I keep having a screw come out just a teeny tiny bit - enough to block my low F sharp/high C sharp key and make it stick, essentially. I have a tiny screwdriver kit so I am able to tighten it every time and it's okay for a while, but it keeps happening. Someone suggested the rod or screw may be the wrong size.
Any ideas?

The rod screw or key barrels could be very slightly bent causing increased friction or binding which in turn could cause the screw to back out. Or the threaded pillar at the threaded end of the rod screw could be rotated so it's out of line or faced off at slightly the wrong angle so the screw can't be tightened without the keywork binding. If it's a rod screw with a point at the threaded end, then the countersink in the key mounted on the point may not be deep enough and that will cause the screw to back out.
Have it checked to be sure everything is running true and rectified if need be.

Because that's not addressing the underlying problem.

Does it play fine when the screw is tightened? It could still be bent or binding a little (spring overcoming it) or one of the other things Chris mentioned, even if it plays fine.
If you use a too small screwdriver (both blade and/or handle) then you might not be able to tighten it as much as it needs to be. Screws rarely back out when completely tightened.
From your description it's not clear exactly what screw is backing out and how it affects the F#/C# key. It sounds like you are not talking about the F#/C# screw itself, but a screw that comes out and then blocks that key, right? Can you post a photo?
If it's not a screw that threads into an in between post (post between two key hinges), then you can put a little bit of low strength Loctite (or equivalent). It might not hold if it's too oily. Make sure it doesn't get into any hinge. Otherwise better to go to a good repairer who can fix it, unless you want to start removing keys and checking for the problem yourself (would need a lot more info to have suggestions)?
