Yep, they are electropolished S/S, coated with anti-seize before installation.

The pic of the rotten stuff I posted earlier shows what happens to regular steel bolts. I did a lot of research for that very reason - the conventional wisdom is no S/S in an iron keel. I discovered that the big Euro builders all use S/S in iron keels. Due to that and the fact they can be easily pulled and examined, I decided to go that way.

Also, I've never heard of an iron keel with S/S bolts falling off due to crevice corrosion, galvanics or anything else to do with the metals, just a lot of talk about how "dangerous" it was, none of it by the way from anyone who actually OWNED an iron keel.

However I HAVE heard of iron keels mounted with steel bolts falling off - one of them was another Columbia 43 in Sausalito.
