Hey Sniper, that"s the Cragar lug nuts I bought, just not from Summit Racing and they wouldn't tighten down my mag wheels. The shanks seem to be a little to long. So I took the nuts down to my local machine shop guy and had him shaved them down a little. Came home put a wheel on and they tighten down good, or so I thought. Mounted up the other 3 mags to 55 foot lbs and took the car for a spin. Drove it 1 mile, came home and checked the lug nuts and most were coming loose. Re-tighten again. This time to 65 foot pounds. Drove the car again 1 mile and returned home. Checked the nuts a second time, same thing coming loose again. Can't tighten them any more past 65 ft. lbs for fear of breaking the 7/16 wheel studs. Anybody got any suggestions? So now I've got $800 dollars worth of Cragar S/S Mags I can't use.
