Cragar SS lug nut trouble

You have the wrong lug nuts. If you compare the lug nuts you have with the ones linked in post # 2, you'll see that the ones you bought have a .68 inch diameter shank, while the correct ones have a .59 inch shank. If you take a look at your wheel specs, you'll see that the lug nut shank diameter of your wheels is .59. (Also, the correct lug nuts are installed with a 3/4 inch socket, while the ones you have are 13/16.)

I don't know why Summit shows the lug nuts you bought as "recommended" for your wheels, but anyway, just get the correct lug nuts. If you ordered the lug nuts from Summit, I'd ask them for my money back on the incorrect nuts you ordered based on their recommendation.

Edit: Also, the wheels will look better if you paint the brake drums black.

This thread has been very helpful to me. When I bought my wheels and tires several years ago I had this same discussion with my local tire store. After several calls to their distributor for Cragar wheels they told me that the conical lug nuts were all that were available and I had to use them. I had some of the correct lug nuts and showed them to them, but they couldn’t order them at the time. I believe my dealer, but I think they got the wrong information from their distributor. Photos of my wheel and a lug nut I just removed. It’s a 13/16” socket size. As you can see, my wheels do not have the tapered seat. The car has been driven very little since the wheels were installed, and only locally at low speeds. There doesn’t appear to be any damage to the wheel. I looked on the Summit site as suggested and found the left hand nuts (9004-4) and am going to order full set (3 bags full) of each. Thanks again. I knew this wasn’t right.

I can speak personally to the need to torque correctly and re-torque the lug nuts. I had just had my high-school ‘65 Dart GoGo into a tire store for new shoes and immediately took off on a 300 mile round trip. On the way back I kept hearing a”clicking” sound and got out a couple time to check the source of the noise but couldn’t see anything to cause it. A few minutes after my last check I sheared 4 lug studs on my left rear wheel at high speed. I was able to get it stopped safely and without damage, but it was a real eye-opener. Thanks again for this post. My new new nuts are on the way.
