These nuts have been attached to my off-road trailer for over 5 years. Just wanted to show what happens to cheap nuts. Rusted a lot more than I expected. Yes, they still hold up my wheel, but they don't look as bright and shiny as they did when new. But given the low price, I shouldn't be too surprised. Now I'm going to replace them with a more expensive version and hope they take better hold. And yes, my jeep's factory nuts are much older and still look like new.
