When looking those up they all say chrome capped. The Acadia ones are chrome capped and some of the caps are loose and rattle when you shake it. They also get stuck in the impact socket.I am using 19302058 on mine. They are freaking expensive tho.
I just have bad memories of the chromed acorn style nuts that came on our 02 mustang. They had caps that would eventually loosen and slide off the steel core of the nut.
