2006 Chrysler 300 Rotor Replacement Question.

So I am going to replace the rotors on my 2006 Chrysler 300. I only have 1 question. There are these, nuts I guess? are on 3 of the lug nut studs that I am not sure how to remove and need to know what tool I need to remove them with. They look like the picture I have linked below but are on top rather than on the side. They are basically shaped like a pyramid that is laid on the 2nd longest side. If I cant get those off, I cant remove the rotor. I am guessing I just need a special socket for my socket wrench to remove it. If you could please just tell me what I need I would greatly appreciate it! Thank you for any assistance you are able to lend me.
