Hi Josh,
316L S/S is better than 316 for welding
applications. The L (low carbon) helps prevent
rust stains at the weld interface.
304 and even duplex S/S (2205, sometimes called
18-8) will be fine for keelbolt washers if it is all that is available.
Cheers, Russ

Dan,Â
Mine came with SS washers. You can most likely
find them on McMaster-Carr or just make them out
of SS sheet. If I was making them I'd just cut
them square. You'll probably want no less than
3/32". There is nothing wrong with anything
thicker. Youâll find cutting SS is a
challenge. A machine shop can make these quick
and easy. When sourcing SS look for at least 316.  316L is even better.
You can make a backing plate with G-10 or FRP
(also available on McMaster Carr). I would use
at least 1/4" and probably opt for 1/2".
It is quite frequent for owners to find that the
"foundation" is not flat or square to the
stud. You can fix this by bedding the backing
plates with thickened epoxy (Six10). It is
short sighted to allow the epoxy to bond the
keel bolt in place. Prevent this by using a
FRP tube cut to act as a protective
sleeve. The sleeve should slide loose on the
stud and tightly in the FPR backing
plate. Tighten the nut only enough to smoosh
the leveling agent (thickened epoxy) out a
little. Let the epoxy cure and then torque the bolts as appropriate.

Hi All, I know this has been discussed many
times here but this is a quick and simple one.
I'm going to be torquing my keel bolts this
spring and I've noticed that the washers/spacers
under some of the nuts are coroding and need to
be replaced. I'd like to change them out for Stainless Steel.
What do you guys have for keel bolt
washers/spacers and how did you get them made?
Thanks!
