Bolt Products passivates their bolts (I assume that's who you're referring too). Note that 316SS won't be that great in nasty marine environs. I'm betting you know that too though...
Bolt Products use Duplex SS in their marine bolts.

The Wave Bolts do look a bit rough when you get them compared to Titt bolts. I do a bit of cleaning up as well to help with corrosion resistance.

I'm working in smaller batches of 20 or so. I use Barkeeper's Friend (oxalic acid) to clean and passivate. I simply scrub them with a rough sponge with water and the Barkeeper's stuff. Polishes them right up. I've also used the stuff to clean up SS hangers that have rust stains on them from PS washers. They look like new when done.

If I were doing larger numbers of bolts, I'd look into running them all in a dishwasher with citric acid (look for dishwasher cleaner) Same idea. You still might need to do some spot scrubbing if there's real dirty spots.
