Lug nut shank diameter?

[Jeff G 78]

Can someone please measure a typical aftermarket wheel shank-style lugnut diameter? I am in search of lugnuts for typical 14x6 slot mags and I need the shank diameter. I can remove a wheel tonight at home, but I really need the info right away. I used to be able to buy them easily, but lately they are really hard to find and when I do find them, they are the wrong length or diameter.

Thanks in advance.
