316 grade stainless steel deck screws - for decks and docks

Why 316 grade stainless steel?

316 grade stainless steel screws are favored due to their corrosion resistance and durability in all outdoor conditions. This steel variant offers the best protection in corrosive environments, which makes it suitable for marine or coastal applications. It is called "marine grade" for a reason. The high quality of 316 grade fasteners ensures long-term reliability with minimal maintenance which makes it the first choice for builders and contractors working in salty or otherwise corrosive climates.

Stainless steel screws with type 17 point for easy driving

Benefits of star (torx) drive

The torx drive's six-point star design makes for easy driving with minimal cam-out. The torx head also makes for better torque transfer as the driver is less likely to pop out as it does with more traditional traditional pozi drive screws. This makes it a preferred choice in decking, fencing and general woodworking project where the head is exposed as the finish looks better and becomes a feature in the work.
