Correct lug nuts with American Racing Wheels

I just bought a used set of American Racing VN504 wheels. I see what looks like the usual 60 degree bevel but I also see a flat recess that looks like a washer might belong there.

Summit says Lug Nut/Bolt Seat Style:

Conical seat - 60 degree

Same as my TT2s. I wouldn’t expect a washer. Can you just send query to AR?
