R4™ Multi-Purpose 316 Stainless Steel Screw

Marine-Grade corrosion protection 

316 stainless steels screws are recommended for applications where extreme corrosion resistance is necessary, such as environments with high exposure to chlorides- such as de-icing salts- and applications within 1 mile of the coast. They are also suitable for use in chemically treated wood and naturally-protected wood such as cedar and redwood.
