Simpson Deck-Drive DWP Wood Screw in #8 x 2-1/2" Type 316 Stainless Steel is engineered for demanding deck, dock, and general exterior fastening applications where superior corrosion resistance is essential. Featuring a flat head profile, T20 6-lobe drive, sharp point, and proprietary box threads, this fastener from Simpson drives cleanly into the wood used in today's deck boards while standing up to the harshest coastal and seaside environments. The Type 316 stainless steel construction resists saltwater, moisture, and chemical exposure - making it an ideal wood screw for boardwalks, exterior trim, fascia, and other applications where standard fasteners would fail over time.

Key Features

• Type 316 Stainless Steel material - provides enhanced corrosion resistance against saltwater and coastal conditions, outperforming standard stainless grades in seaside and marine environments
• Unique box thread design with raised-ridge technology - greatly reduces driving torque, so installers can drive more screws on a single battery charge and work more efficiently on large decking projects
• Specially designed sharp point - penetrates hardwood products with ease, eliminating the need for pre-drilling in most applications and saving significant installation time
• T20 6-lobe drive - delivers a secure bit fit, resulting in easy, controlled driving and extended bit life compared to standard drive types
• Flat head profile with 0.335 in. head diameter - sits flush with the surface for a clean, professional finish on deck boards, fascia, and exterior trim
• Compatible with wood, engineered wood, and polymer materials - versatile enough to handle the wide range of decking products used in modern construction and renovation
• Available in a variety of sizes - suitable for fastening standard deck boards as well as fascia and trim applications, giving contractors and DIYers a consistent fastener system across the project

Why This Product

• Built for coastal and seaside environments - Type 316 stainless steel is specifically recommended for applications near saltwater, where chloride-rich air and water would accelerate corrosion in lesser-grade fasteners, protecting the structural integrity of your deck or dock over the long term
• Reduces driver fatigue and battery drain - the box thread design with raised-ridge technology significantly lowers driving torque, meaning less strain on the installer and fewer battery changes during large-scale decking installations
• Handles hard and engineered wood without pre-drilling - the sharp point is engineered to penetrate dense and composite deck board materials directly, streamlining the fastening process and reducing labor time
• A single fastener solution for multiple exterior applications - equally suited for deck boards, docks, boardwalks, fascia, and trim work, this screw simplifies material planning and keeps your fastener inventory consistent across a wide range of exterior projects

Frequently Asked Questions

What makes Type 316 stainless steel the right choice for exterior fastening applications?

Type 316 stainless steel offers a higher level of corrosion resistance than standard stainless grades, making it particularly well suited for seaside, coastal, and marine environments where exposure to saltwater, humidity, and harsh weather is constant. It is the recommended material choice when extra corrosion protection is needed for deck, dock, and outdoor applications.

Can this screw be driven without pre-drilling the wood?

Yes. The sharp point on this Deck-Drive DWP Wood Screw is specifically designed to penetrate hardwood and engineered wood products directly, making it suitable for driving without pre-drilling in the majority of wood used in today's deck boards and exterior applications.

What bit do I need to drive this screw?

This screw uses a T20 6-lobe drive. A T20 driver bit is required. The 6-lobe drive design ensures a secure fit between the bit and the screw head, which promotes easy, consistent driving and helps extend the usable life of the bit.

Is this screw suitable for fascia and trim work as well as standard deck boards?

Yes. The Deck-Drive DWP Wood Screw in Type 316 stainless steel is offered in a variety of sizes and is designed to fasten both deck boards and fascia and trim. Its flat head profile sits flush with the surface, providing a clean finished appearance appropriate for visible exterior trim applications.
