Overland Rock Rail j-nuts

Does anyone know where I can buy the j-nuts that are used to fasten the Overland rock rails onto the body? Also, which specific shape and size are they? Mine were in such a bad shape that I had to drill them out, so I just threw them out a while back when I removed the rails.


I found out, when I removed them, that the rocker panels have big holes in them underneath. I was going to replace them with 2x6" steel, but I need to pass inspection this month, so I thought I'd just cover them up with the rock rails until I can get someone to sell me some steel.

if you have rock rails, why even bother with replacing the rockers? a good set of sliders requires you cut out the rockers anyways.



mscdirect makes/sells j-nuts, cage nuts, etc.

The rock rails reduce ground clearance and I'm not sure how well they'll fit, since I've trimmed the fenders a bit. I might have to shorten them to get things to align up, for nicer aesthetics. Also, I was thinking that I ought to cut out the rockers and line the inside with rust converter to keep the rest of the body from rotting away.


It seems that I can order j-nuts from plenty of online stores, but I still don't know which j-nut I should order. If anyone knows, it'd help a lot.

Please will you explain why you think rust converter will stop rusting Andri?

I don't think that it will stop rusting. I would assume that it might slow down the spread from the area to which it is applied. Otherwise, what would be the point of applying it?

Thanks Andri.

I don't know enough about Rust Convertor to answer your question I'm afraid.

Have you heard of Owatrol Oil?

M8 are the size used, they are also known as 'spire nuts' - well they are in England.

Thanks! It's also helpful to know an alternative name for them. Now I just have to figure out which shape I need to get. I guess I'll just order them in different shapes and see what fits.

Hey, thanks! I tried to find something on the rock rails on wjjeep.com, but I must have glanced right over it or searched for the wrong thing.


Here is a picture of the nut with measurements:
