Cragar SS lug nuts

Hey all, I tried to install my Cragars the other day, and the lug nuts that are on my car, on Centerlines, don't fit in the hole in the rims. These are small bolt pattern rims. The holes in the Cragars seem to be approximately 1/2" diameter. Flat face rim, not beveled. 7/16" studs. The shank on the lug nuts is about the standard 0.680". Are there special lug nuts that will fit this application?

TIA.

Mark
