SS screws, 3xx series is least reactive. Al and Zn do not typically have a pronounced galvanic reaction, but this could change in areas with acidic rain, coastal areas, etc - depending upon the specific alloys.

When I worked in Colorado, I got to see a lot of instances of galvanic corrosion where aluminum and galvanized were in contact above grade. Colorado is pretty dry, and far from a coast, so my answer has to be "Yes, they do corrode together."

I use an all-in-one bar hanger it comes with a mill finish aluminum screw and it also comes in copper if you using copper gutters ;) it goes with 5" and 6" K seamless gutter system.
That is a nice looking hanger, who has them? Your link just gives me a picture but no website Mike

I am a contractor south of Boston, I usally have Ryan Seamless Gutter drop them off with gutter list. I'm sure that where you live that a Gutter supply as them. There is one site that has them, I'm not sure if you can order them through Berger. Heres the website: http://www.bergerbros.com/products_k.html
