Simpson Deck-Drive DWP Wood Screw in Type 305 Stainless Steel is a purpose-built fastener from Simpson designed for deck, dock, and general exterior wood applications where superior corrosion resistance is essential. The #10 x 2" flat head screw features a T25 6-lobe drive, sharp point tip, and unique box threads that work together to deliver fast, reliable installation into the majority of wood species and engineered wood products used in outdoor decking and trim work. When moisture, weather, and long-term durability are priorities, this stainless steel wood screw offers the protection and performance that exterior projects demand.

Key Features

• Type 305 Stainless Steel material - delivers strong corrosion resistance for deck, dock, and exterior applications exposed to weather and moisture, extending the life of the fastened assembly.
• Unique box thread design with raised-ridge technology - greatly reduces driving torque, so you can drive more screws on a single battery charge and reduce installer fatigue on large decking projects.
• Specially designed sharp point - penetrates hardwood and dense wood products with ease, eliminating the need for pre-drilling in most applications and speeding up installation.
• T25 6-lobe drive - provides a secure bit-to-fastener fit that reduces cam-out, results in an easy, consistent drive, and extends bit life over the course of a project.
• Flat head profile - sits flush with or below the surface of the decking material for a clean, snag-free finish that is both functional and visually appealing.
• Compatible with wood, engineered wood, and polymer materials - gives contractors and DIYers flexibility across a wide range of modern deck board products without changing fastener types.
• Available in a variety of sizes - including options suited for fascia and trim, making this screw family a versatile single-source solution for exterior finish work.

Why This Product

• Built specifically for exterior wood fastening - the combination of sharp point, box threads, and Type 305 stainless steel makes this screw engineered from the ground up for deck boards, docks, and outdoor wood structures rather than being a general-purpose fastener adapted for outdoor use.
• Reduces job-site downtime - the raised-ridge box thread technology cuts driving torque, meaning cordless drills and drivers go longer between charges, keeping your crew working efficiently on large decking installations.
• Corrosion resistance where it counts - Type 305 stainless steel construction provides the elevated protection needed for exterior environments where standard coated fasteners may degrade over time, helping maintain structural integrity of deck and dock assemblies.
• Broad material compatibility - works across wood, engineered wood, and polymer decking materials, so this single fastener can serve multiple board types on the same project without switching hardware.

Frequently Asked Questions

What types of materials can the Deck-Drive DWP Wood Screw fasten?

The DWP is designed for use with wood, engineered wood, and polymer materials, making it suitable for the majority of deck board products available today. It is also offered in sizes appropriate for fascia and trim applications.

Why does the box thread design matter for my project?

The unique box threads with raised-ridge technology are specifically engineered to greatly reduce driving torque compared to standard thread profiles. This allows you to drive significantly more screws on a single battery charge, which improves productivity and reduces fatigue on large exterior projects like decks and docks.

Is Type 305 stainless steel appropriate for all exterior environments?

Type 305 stainless steel provides strong corrosion protection for deck, dock, and general exterior applications. For seaside and coastal environments with heavy salt exposure, a higher-grade stainless steel option would be the more appropriate choice - the DWP line is available in Type 316 stainless steel for those demanding conditions.

Do I need to pre-drill when using the DWP Wood Screw?

No pre-drilling is typically required. The specially designed sharp point is engineered to penetrate hard wood products with ease, allowing for direct installation into most deck board materials without additional preparation steps.
