You might consider making your own. Not all that difficult once a die is made. I have made many from bronze rod. SS is a bit trickier.

Thad, I gave your source a call.....very nice people. They didn't have any 7/16" stock made up and I only need two bolts. I spoke with Andy and he filled me in on how to make the fin heads.....So Tull, looks like I will be rolling my own. Thanks!

A fin head bolt is an upscale version of a carriage bolt. Instead of a squared section of shank just below the rounded bolt head, a fin head bolt has thin "wedges' like the web between your thumb and forefinger from the shank to the flat bolt head. These can be used for bolting on something like a cleat where you want to keep a smooth surface (no slot like in a slotted bolt) varnished.

Reportedly they are more water tight than a carriage bolt (for deck purposes, not below the waterline!).

Do you drive the fins across the grain or with the grain?

The fin head bolt was developed by Herreshoff and used for floor timbers and keel ballast timbers. Why wouldn't they be used for below water applications?

With the grain, and I am also wondering why they could not be used below the waterline

I know you believe you understand what you thought I said, but I'm not at all certain that what you thought you heard is not what I meant...

I was once told that the fin-head bolt, used say, on a horizontal surface, will do a much better job self sealing its hole than a carriage type of bolt, and would not require a bung. If, however, it were used where large quantities of water existed on one side, and large quantities of air on the other, a bung would be required to prevent a leak.

Maybe true, maybe not.
