[QUOTE="bassboy1, post: 216958, member: 55"] Aluminum would be better from a dissimilar metals standpoint, but stainless hardware is adequate. Now, in the SS/aluminum pair, the stainless is the cathode, and the aluminum the anode, meaning the more noble stainless will corrode the aluminum. However, given the quantities in question (a whole boat worth of aluminum vs. a small SS bolt), the effect is going to be very minimal. Were the situation reversed, say an aluminum bolt in a stainless steel hull, the results would be different, and the bolt wouldn't last very long. [/QUOTE]
