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.
Received my order today Fri Mar 5, as usual excellent service with an excellent product,liked the idea that you guys sold the grill as a 2 piece rather than having to order two seperate pieces,like some of the other suppliers, will be dealing with you again in the future.Cheers Bill

Just purchased the Black "slat" Grill to replace the standard chrome slat grill on my R56, I installed it with the original chrome trim pieces, looks fantastic for $100. Not knowing what I was doing at first and it still only took 10 mins. to install.
