These are stock lug nuts with the part number for aluminum wheels.

Hi, and thanks to all who have responded to this question.

The wheels are aftermarket (bought new in 1972) and I'm not sure I ever knew the manufacturer.

The important thing here, as has already been pointed out and questioned, is the lug nut's shape. That said, these artermarket wheels take a taper ended nut similar to that of the OEM's steel rims.

Thanks again, everyone!!

Do the existing lug nuts fit properly? Sometimes you will have to match up the wheels with the lug nuts making sure you are engaging enough thread on the studs as well. The tapered shank type are a little harder to match up, especially when buying on line. It took me a while but I finally found a set of lug nuts that match up perfectly with my Watanabes without paying the price they wanted.

Hi, geezer

Yes...I state that because over the past 40 years they have been viewed by various tire-techs without comment. Additionally, I've never been witness to any visible damage to the rims and, to date, I've never had any problems (ie loose rims) except for the rust issue as mentioned earlier.

Cheers,

George
