Simpson Deck-Drive DWP Wood Screw in #10 x 2" with Type 316 Stainless Steel finish is a heavy-duty exterior fastener engineered for deck construction, dock building, and general outdoor wood applications where superior corrosion resistance is a priority. Featuring a specially designed sharp point and unique box-thread profile, this flat-head screw drives cleanly into a wide range of wood and engineered wood materials - delivering a secure, low-profile finish that holds up in even the most demanding coastal and seaside environments. The T25 6-lobe drive keeps the bit locked in place during installation, reducing cam-out and extending bit life for high-volume fastening work.

Key Features

• Type 316 Stainless Steel material and finish - provides exceptional resistance to saltwater, moisture, and harsh outdoor conditions, making this screw the right choice for seaside, coastal, and dock applications where standard fasteners would corrode prematurely.
• Unique box-thread design with raised-ridge technology - greatly reduces driving torque so you can drive more screws on a single battery charge, boosting productivity on large deck or dock installations.
• Specially designed sharp point - penetrates hard wood products and dense engineered wood with ease, eliminating the need for pre-drilling in most applications and speeding up installation time.
• T25 6-lobe drive - delivers a secure, snug bit fit that minimizes cam-out, results in an easier drive stroke, and extends the usable life of your driver bits.
• Flat head profile with 0.335" head diameter - sits flush or countersinks cleanly into deck board surfaces, producing a neat, professional finish without raised hardware that could snag or catch.
• Compatible with wood, engineered wood, and polymer materials - provides versatile fastening performance across the variety of decking products used in modern construction, from dimensional lumber to composite-compatible substrates.
• 2" length in #10 screw size - sized for typical deck board fastening applications including fascia and trim work, providing solid holding power without over-penetrating lighter material assemblies.

Why This Product

• Built specifically for corrosive outdoor environments - Type 316 stainless steel offers a higher level of corrosion protection than standard stainless grades, making this screw ideal for docks, boardwalks, and coastal deck builds where exposure to saltwater and humidity is constant.
• Engineered to reduce fatigue on battery-powered tools - the box-thread geometry actively lowers the torque required per screw, which means longer run time per charge and less wear on both the tool and the installer during large-scale exterior projects.
• Designed for today's deck board materials - the combination of a sharp point and box threads makes this screw ideally suited to the full range of wood species, engineered lumber, and polymer decking products commonly used in modern deck and dock construction.
• Versatile sizing for decking and trim work - available in multiple sizes, the DWP Wood SS screw handles not only primary deck board fastening but also fascia and trim applications, reducing the number of different fasteners needed on a single project.

Frequently Asked Questions

What is the difference between Type 316 and standard stainless steel for outdoor fasteners?

Type 316 stainless steel contains added molybdenum, which gives it superior resistance to saltwater, chlorides, and harsh coastal conditions compared to standard Type 304 stainless. This makes it the preferred choice for docks, boardwalks, and decks in marine or seaside environments where standard fasteners would corrode and fail over time.

Do the DWP box threads require pre-drilling before driving?

No. The sharp point and unique box-thread design work together to penetrate wood and engineered wood products without requiring pre-drilling in most applications. The box-thread geometry also significantly reduces driving torque, making installation faster and easier on battery-powered tools.

What materials can these screws be used with?

These screws are suitable for use with wood, engineered wood, and polymer materials - covering the broad range of decking products used in modern construction, from traditional dimensional lumber to engineered deck boards. They are also appropriate for fascia and trim applications.

What driver bit do I need for the T25 6-lobe drive?

These screws require a T25 Torx-compatible 6-lobe driver bit. The 6-lobe drive geometry provides a secure fit between the bit and screw head, reducing cam-out during installation and extending the working life of the bit - particularly beneficial during high-volume deck or dock fastening projects.
