This is a difficult application to suggest the rivet nut material for, since the bolt is stainless steel while the roof is aluminum. There is some galvanic corrosion concerns, but more important could be the strength of the rivet nut. The stainless steel rivet nut is the strongest rivet nut we can offer, and paired with a stainless steel bolt, then that means more likely than not, the aluminum roof will fail (due to being the softest material) before the stainless steel rivet nut or stainless steel bolt.
