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.
Got a set of these as opposed to going the "Autostrap" direction as mentioned in many of the forums. They were a snap to put on and were a perfect fit. Thanks guys for putting them on your list!

Great first mod knocks out two birds with one stone (great power gains, amazing sound enhancement) for a great and really low price! 10/10 would recommend

In the MINI community there's three stores that I get my items from, and every time, I find the best deals here! Website experience is amazing, providing great detail on what each item does to your MINI. Customer service is also fantastic! IF your ever hesitant to ask a question about a certain part, go ahead and give them a call!
