Those are called rivets which are extremely durable and strong when installed correctly using a rivet gun, however, standard stainless bolts and nuts sourced from a local hardware store will work just as well.
I bought these thinking that they might be cheaply made, but I was really surprised. Instead, I read on the box that they were made in Germany; hence, the reason for the high quality. If you buy these wheel center caps, you will not be disappointed. They are very high-quality.

Very good experience. Shop, order, received the part I ordered and satisfied
That's it!
Thanks!

So as a mini enthusiast, of course I try to do the up keep myself. I broke a bolt replacing the rubber gasket on the valve cover. 2 places on this earth have it. Here and of course mini dealers. Mini dealers have no interest in replacing parts in my 2011 mini cooper. They want me to buy a new one.
I was happy to buy the parts right here, have them shipped out and arrive in 3 days. Well done you lot for helping the regular weekend car mechanics.
