Art, these steel head pop rivets have a head size of 3/8". Most aluminum pop rivets you find will have a very rounded lip on the outside of the head. These steel head rivets slope down to a near flush joint with the surface. The more rounded edge found on an aluminum pop rivet may cause airflow separation, creating an inconsistant low pressure area above the static port. These are a piece of cake to pull. Additionally, as I mentioned before, these rivet heads are treated in some manner. They appear as glossy as the alclad aluminum they are affixed to on my project. If you are worried about rusting, scuff the head up with a scotch pad and prime with NAPA 7220 rattle can self etching primer, found at your local NAPA store.
