Cragar lug nut question

[427TJ]

I have a set of new Cragar S/S's with the oval uni-lug setup. I already have a set of new chrome lug nuts and washers that I used on a set of American Torque Thrust wheels and they fit through the oval holes in the Cragars. I'm wondering if the uni-lug design requires a special lug nut or can I use the ones I already have?

Excuse me if this is a no-brainer but I've never had uni-lug wheels and I don't want to screw up my wheels or studs.

Thanks in advance!
