The only problem using that will be tightening the nut. A lot of amos only have enough room for a something the size of a philips head screw...
I was concerned about the amp receiving maximum exposure to air as well. I went with Nylon spacers between the amps and mounting surface. This in conjunction with stainless screws and no problems after a few years of use. And in very rough water conditions as well. You can find Nylon spacers in the hardware section of Home Depot.
Cool. Good idea. Glad it seems to work.
There is this style, used for mounting ignition boxes / coils in rough conditions. This would space it up and absorb shock as well.

Yeah, that's the 1/4-20 size. They have a #10 also. Still might be a little big. And you're right, the cooling fins tend to be right against the screw. If it worked that way, it would be secure - can't deny that!
