I have the factory Alcoa wheels. The lug hole has a tapered hole for a acorn style lug nut. But the face of the wheel has marking from a flat (washer enclosed nut) being used. Does anyone know what is the correct lug nut for my 1997 F350 4x4 5.8?

 

As far as I know, the wheels use conical style lug nuts. shaped like \_/ on the end.

 

I found a OEM parts finder. It shows my year and model
Calling for a flat lug nut with a enclosed washer. The wheels have a tapered hole for a acorn style nut. Does anyone have a picture of the factory lug nut? Thanks

 

Acorn style lug nuts because these trucks were NOT hub centric.

Hub centric wheels use the washerd style lug nuts, like what a dually uses

 

Thank you very much!

 

Where can I find the correct OEM lug nuts? I've looked almost everywhere with no luck!

 

Any junk yard will have buckets of them. NAPA,Advance, AutoZone, Orieleys, etc. Or you can also go to ford
