Screws made from 316 grade stainless steel are made to resist corrosion that comes when building close to the ocean. Salt water is especially corrosive and will destroy most materials. When working on houses, decks, docks, boats and other seaside projects, it is best to use type 316 stainless steel fasteners.
Sharx brand screws are best used in composite materials, fiberglass & engineered wood products: such as plywood, OSB, laminated wood veneers and wood substitutes.

316 Stainless Steel - Wood Screws Salt Water SafeType 17 notched point for fast penetration Self-countersinking bugle head Square drive recess reduces driver cam-out Threaded approximately 2/3 of shank on most sizes Deep coarse threads for better hold Use with cedar, redwood, engineered wood and preservative treated *Type 316 Stainless Steel should always be specified for salt water applications. 316 grade stainless steel has a lower carbon content than 18-8 type stainless (302HQ, 304 and 305) and contains molybdenum for superior corrosion resistance in salt water and other highly corrosive environments. It is the grade of stainless steel to be specified in any seaside application to prevent rusting & bleeding through. Important Installation Instructions: If the screws are to be driven by a screw gun, be sure the bit is securely seated in the square recess of the screw. Start slowly and gradually increase speed until the head is driven flush. A high driving speed increases the chance of stripping the square drive recess. If the tool has an adjustable torque collar, use a piece of scrap lumber to determine the proper setting needed to drive the head flush with the surface. This will prevent twisting off the screw head.
