Lug nuts

Are the lug nuts unique to the Mach 1? I bought some FR500 wheels and the lug nuts (1/2 x 20 with 6-spline socket) that I bought from the local auto parts store won't work. They run out of thread before they tighten down on the wheel. I compared them to the factory OE lug nuts and the OE ones are much longer to accommodate the longer wheel studs.

I reordered some from American Muscle, but the tech specs list them at 1.3" long which seems like it'll be about the same length as the auto parts store ones I bought that won't work. I'm wondering if I should cancel my order.
