washer for keel bolts
I am replacing the backing plates, washers and nuts (while I'm at it) on my keel bolts. The bolts are in great condition (from what I can see) - but for peace of mind sake I am replacing the hardware.
Having custom stainless backing plates made (getting quotes now - not sure if I should go with 304 v 316 as I read that 316 is subject to stress issues), but am looking for washers and nuts - the bolts I am replacing are 5/8" (for some strange reason my keel has 8 bolts - where 2 are 3/4" bolts, and the rest are 5/8). At any rate, for the washers and nuts do you think I can use 18-8 stainless or do I need to go with 316? What is difference in strength (if any). Of course the 18-8 are easier to obtain. How about Monel (McMaster Carr sells them for $7 a pop!)
Appreciate any thoughts here.
