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.

These guys are the best. Their knowledge of these cars is over the top. You get so much more than parts here; you get knowledge and amazing customer support. I just won't deal with anyone else anymore, this place is that good. Than you Aaron and everyone for making a great place to keep all my MINI's going strong!
