I have a 3 year-old catamaran
which requires that I re-fasten every deck
fitting due to 1) to lack of coring protection at any of the holes & 2) many of the heads of screws are slightly to badly rusted. I suspect the machine screws are cheap
, imported 18-8 grade. Some screw heads look almost like mild steel
they are so rusted!
As I don't want to do this twice, I have been researching crevice corrosion
& the different grades of stainless. A posting
somewhere here recommended US made 316 stainless from B & S Bolt in Virginia, but 1/4"-20 x 2" machine screws (for example) are almost $9.00 each! Would the best reasonable choice be imported 316 from a reliable source?
