this is 304 Or 316?
316. No rust yet and they are on a boat in the Caribbean - rust central.
Can I use s/s carriage bolts to bolt wooden boat frames to floors. The bottom planking and a lot of other parts are screwed with silicon bronze. I will leave the s/s bolts unpainted?
No need to paint.
I have used these carriage bolts to bolt wood to the bed of a truck and they worked great. No issues at all and be sure to use ss nuts, washers etc so that there is no issue with corrosion.
I am using SS carriage bolts in my glass bottom boat that we are presently building in Belize. We are using them to bolt timbers to floor members. We are also leaving them unpainted and expect that even in the salt water conditions that they will be fine.
S/S Carriage Bolts
I use these when building outdoor furniture made from red cedar and pressure treated pine. They work great and hold up very well, even in saltwater environments. They never stain the red cedar, which typically stains using non-stainless hardware and fasteners. Since they are stainless steel be mindful if you use stainless nuts, that they can "gall" and seize up. To avoid this, use a little anti-seize compound on the threads. Just use common sense and you'll be fine. I've been purchasing these for years and never had any issues. I will continue to buy these for years to come!
Great on fixing my pontoon boat.

I ordered thses SS bolts along with washers and nuts for a swing I was building out of cypress. The swing turned out great and the SS bolts also look great. Items arrived quickly and well packed. All in all a very pleasant experience and I will order from Jamestown again.
