They're galvanized and coated with some specail Zmax coating or something (no idea what that stands for). But according to Simpson's website - they are corrosion resistant... but even so, I'm not worried about corrosion

That's all I needed to hear, thanks man.

The strong-ties may be corrosion resistant themselves but that doesn't mean they won't cause corrosion when in contact with aluminum. The two metals should be isolated from each other.

If you read the last answer on there it says "Zinc is often the metal of choice for the anode"... that is the coating that is on the galvanized brackets and works in the same manner

Yes zinc is used for anodes on motors... The anode is "sacrificial" meaning it is meant to corrode away instead of metal on your motor. It prevents galvanic corrosion of your motor because it has a higher electrode potential and corrodes faster than steel or iron when emersed in an electrolyte (fresh water and to a larger extent salt water) by metalic ion migration. When you screw your StrongTie into wood the wood does not conduct electricity therefore the zinc no longer corrodes but does the reverse and prevents corrosion of the StrongTie. But screw it into aluminum that is bathed in water it becomes extremely corrosive. Basicly your aluminum will turn to a white dust.

Sure, if you're paying, lol. I'll see what I can find, but a quick search wasnt productive.

You don't always have to buy it if you are resourceful. If you look you can find good scrap aluminum everywhere.

As for the nylon washers here is what i found on the first page of a Google search:

You can also find them at most any hardware store.

Zinc Chromate causes corrosion?? Funny, I used Zinc Chromate as the primer for my aluminum boat... may be something different, but I don't think it causes corrosion.

Yes you may have me on the chromate part. But trust me using zinc treated hardware on your aluminum boat WILL corrode it.

Here's a good example. This is an aluminum alloy rim on my truck. Look where the weight was attached to the rim to balance the wheel. See all the corrosion around it. The weight may not be zinc, but the same will happen to your boat wherever you use zinc hardware. On my thick wheel rim the corrosion is just ugly on the relatively thin aluminum of a boat... well it's your boat do what you wish.

I was looking for something totally different, I'm an idiot.

So it's round, not in the shape of a strong tie or something (I imagine people really laughing now) - I just put a washer under the strong tie, and above the aluminum? How many under one strong tie? Would be really helpful to see someone that did it. Paging anyone out there...

Yes use the nylon washer in between the strong tie and the aluminum and use aluminum or stainless steel screws. Those screws are a little more expensive than regular screws but they are worth it in my opinion.
