Scope Ring Screw Rust

[brolo]

I just finished a week in the woods, and my rifle came back with rust in the scope ring screws. The rings are Nightforce XTRM Ultralite Uni-Mount with stock screws degreased and loctite applied. The rest of the rings, mount, scope, and rifle are fine.

-how do I fix it?
-do I need new screws?
-how do I prevent it from happening again?

Looks extra secure to me now. You could always do a bit of nail polish on top and the bottom if you’re concerned about water and rust.

Since it's just a little rust, you can easily clean and prevent them from water to avoid rust again. Changing the screws is not needed

Ive had this same exact issue with ring screws a few years ago. I read to use stainless screws if going into aluminum.
I ended up emailing Warne with a pic and they sent me replacement screws, free. No rust since. Screws are mass produced so sometimes we end up with some with weak plating, most likely replacing them with the same will stop it.
