I know this is kind of a trivial question. I want to get rid of my old rusty lug nuts on my 51 F1, but have no idea what kind I can purchase. What is the thread pattern and how big is the stud? I tried to do some measuring but I'm just not 100% sure on this one.

 

According to the Parts Catalog, they're 1/2 x 20.

 

Thanks! I can stop scratching my head now. I had no idea there were so many different sizes and thread patterns available. Thanks again!

 

You can stop by any local tire store and they can hook you up with the right parts.

 

Be aware, you can buy 1/2-20 lug nuts with either a large or small wrench size. I ended up with half of each! Either will work but get all the same!

 

And make sure they are 60° nuts, not 90° nuts. Stu

 

Also I think the 1/2-20 for Dodge and Chevy are shorter than a Ford.
I found that on getting them for my F2
