i'm buying some new wheels and tires for my f100. what lug nut thread do i need to get? 7/16-20 RH in. or 9/16-18 RH in? thanks.

 

I believe the studs OEM lug nuts thread on are 1/2" X 20, SAE r/h thread.

Any tire shop will have your wheel nuts.

 

Dennis, Down here we call em lug nuts. If you say wheel nuts we wouldn't know what you were referring to.

You might get a box full of wheel bearing nuts.
Should you order LUG NUTS be sure to tell them
what wheels by brand you have and in aluminum
or steel. Remove all possible errors that can and
will happen.

 

That's true. "Terminology is Everything"...... Eh !

This site says both

So true the wrong words can screw things up. Yesterday I sent the wife
to get cam assembly break in grease, comes back with a bottle of oil additive
with zinc you add to your oil to break in the cam. Oops me wrong can't blame
a woman and get away with it. Stop everything, wash up and exchange for the thick moly base grease. This is with the old lifters that I cleaned and reinstalled, being extra careful even with pre oiling.

On lug nuts with steel rims if you use the smaller size you can still see the rim taper, this isn't good. Order the correct size, something to think about.

Mil1ion; I see you have 6 green squares, I must be a retard still holding on the one freebie they gave me.
