A4 (316) marine grade stainless steel hardware for the jobs where corrosion is the primary design constraint - boats, jetties, coastal buildings, harbour installations and anything within reach of salt spray.
A4 (316) is the grade specified by yacht builders and coastal engineers for a reason: the molybdenum content prevents chloride pitting that will destroy A2 (304) in a marine environment inside a season. Hex bolts, carriage bolts, socket caps, dome nuts, nyloc nuts, flat and Form C washers - all A4 (316), all UK stocked.
