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.
out of the box and snapped right on -- 5 minutes...looks great and goes with the black jack on the roof.

My hitch for my R53 came in today and 3 hours later it is installed and the car is all back together. The fit and finish are excellent and I couldn't be happier with the product. The only problem I had is that the instructions mention zip ties and replacement trim mount clips but the little Baggie included in my box was empty. Someone forgot to pop the parts into the bag before tossing the bag into the box. Didn't really effect me because I didn't break any trim tabs and I have PLENTY of zip ties.
Thanks for a great and unique product that makes the ownership of our quirky little MINIs even better.

There really isn't a better place to buy mini accessories than Out Motoring! They have always been extremely helpful and always send high quality products. I will never buy parts for my mini from anyone else.
