They are AN470 aircraft rivets Howard, they come in a number of grades depending on the material you are riveting, I use soft grade rivets as I mostly use 5005 sheet for panel work. If you try to use the harder grade rivets with reasonably soft sheet you will mark the material surface when trying to set them, and unlike steel rivets which you set red hot, Aluminium rivets are set cold. I did show some details of the tools and rivet gun I use in another post earlier on in this thread.
