Wing nut thread size '51 ford air cleaner
 

Have you ever dropped the air cleaner wing nut on top of the engine. Well I did and it crawled away. Anyway, what is the thread size? The local parts store probably has one. Thanks In Advance!

I believe they are 8-24. Your local Ace hardware would have them also.

That seems awful small. I'll dig out my stock air cleaner and make sure.

It almost has to be something near 1/4-20, no?

Most of the ones I've ran into were 1/4 - 20, maybe 1/4-28

That would be my guess, but the stock aircleaner from my '51 is the original, so I'll have the definitive answer.

Probably 1/4-20 on the bottom to screw into carburetor, and the wing nut end of that stud is likely 1/4-28. My guess, and I'm stickin' to it!

I dug out the orignal air cleaner for my '51 today. The top nut is definitely 1/4-20. It is a stamped wing nut with traces of bronze paint that was used on the engine. It was greasy and dirty so I left it to soak overnight. I can post a picture of it if you need to see it.

Thanks for all the information on the wing nut. Will be getting a new one soon!

Hi, is it a solid wing nut or a pressed steal one ?

Re: Wing nut thread size '51 ford air cleaner
 

Pressed steel. As I mentioned above, I can post a photo if needed.
