Rusting screws on UM rings

[Formidilosus]

I live on the Oregon Coast too, I figure the rust is an extra thread locker protection

It’s the best. I actually used to (20+ years ago) purposely try to get ring screws to rust for that very reason.

Not if you thread lock them as you should.

Yeah I thread locked them as per recommendations from all you guys

Now that I degrease all screws before mounting scope they all easily rust.

Just about every screw on rings, bows, etc are all made from carbon steel. Carbon steel will rust. Another thing you could do if you are truly worried about it, is put some mineral oil on them.

Almost all of the ring screws on rifles I use rust. Degreasing accelerates it. Nail polish can help hide/prevent it somewhat by sealing the metal. Rust is an excellent thread locker.

They’re steel screws that aren’t nitrided anymore for good reason, and degreased from the factory. Which means they like almost 100% of ring screws on the market, will get surface rust.

Their website still says that all hardware is nitrided to prevent unsightly rust

I know and in theory it works but in application, most hardware I have used that is nitrided will still rust the same. The best thing to do, is replace hardware with titanium or use some mineral oil in the threads and on the outside.

Wouldn’t mineral oil in threads reduce the ability for it to lock the scope up tight?

I used to worry about this with my bow. I even payed for a titanium bolt upgrade. Having been down that path, I wouldn’t do it again. Sealing the screw heads with nail polish has been enough

I haven't ran into this issue if proper torque is applied.

I completely forgot about the nail polish

you can also use boot wax, i dont personally but i have a good mate who dose to his screw tops to stop it. Think its like a honeycomb boot wax or something to that effect

That was posted for Form. He posted that the hardware is not nitrided.

It was discovered that the Nitride process was detrimental to the strength of the bolts. Rendering them weaker than a standard bolt. The overall torque caused the bolts to potentially break. It was a learning process.

I'm pretty sure all my rings that have seen a fair bit of exposure have some surface rust. Makes me think they are less likely to vibrate loose..

Understandable, but Unknown Munitions should probably remove that from their description.

Maybe a crazy idea… but a lot of suppressors use Inconel so why not consider for other hunting equipment used in these harsh environments?

I work in the oilfield and we use a ton of Inconel raw bar stock and weld inlay in highly corrosive environments on equipment like frac stack valves with great success.

If interested reach out and I can let you know what our cost would be to make these parts at our machine shop.

Either get your screws refinished with Cerakote or a real parkerized job to keep them from rusting.

Is stainless not a option?

Is stainless not a option?

Keeping in mind it'd be stainLESS not stainPROOF depending on the thread pitch there might be a material spec that could work for the torque and not yield. High grade steel screws are stronger than high grade stainless, both of which are stronger than crappy versions of both materials.
