Question by: Kirk M on Dec 31, 2025, 10:27 AM
So this nut, it's made of carbon steel, right? Does that hold up okay if it gets a little surface rust?
Answer by: Customer Support on Jan 2, 2026, 9:35 AM
Designed with a Zinc Clear Trivalent Chromate finish, it's got a Dura-Kote plating, so it should resist corrosion pretty well, even if you see a little surface rust.
