When building near salt water, common stainless steel fasteners just won't cut it. Marine grade 316 stainless steel has been used for years in wooden boat construction and repair because it is the best performing alloy in terms of corrosion resistance. There are several grades of stainless steel, each with a different mix of metals in the alloy. Only 316 stainless steel contains molybdenum, which increases corrosion resistance, and is especially effective when exposed to salt water.
If your building materials are designed to stand the test of time, it only makes sense to use a 316 stainless steel fastener that is designed to match that long life expectancy.
