are they cone shaped or ball shaped?

i got some from autozone cone shaped but the contact area is a thin line

then i checked the RL lugnuts and they seem to have better contact area i cant tell if they are just different angle or actually curved contact surface

can anyone take a picture of the lugnut that came with 2016 RLX please

 

This set on ebay has the same part number as the RLX lug.

If I'm.not mistaken. All OEM style wheels use ball seats

 

Autozone nuts won't work, I tired to get some. They are $7 at the dealer, I had to buy 4 to replace the lock nuts.
