A4 (316) marine grade stainless steel fasteners for the environments that break A2 (304): coastal fencing, jetties, boat fittings, pool and spa hardware, and any structure exposed to salt spray or salt-laden air.
A4 (316) contains 2 - 3% molybdenum, which prevents the pitting corrosion that eats through A2 (304) in chloride-rich environments. Hex bolts (DIN 931 / DIN 933), socket cap screws (ISO 4762), machine screws, nyloc nuts (DIN 985), dome nuts (DIN 1587) and flat washers - all A4 (316), all stocked.
