Simpson Deck-Drive DWP Wood Screw in #10 x 3" with Type 305 Stainless Steel finish is a high-performance fastener engineered for deck boards, docks, boardwalks, and general exterior wood applications where reliable corrosion resistance is essential. Featuring a sharp-point tip and proprietary box-thread design, this flat-head wood screw drives cleanly into the majority of today's deck board materials - including wood and engineered wood - while reducing the torque required so you can complete more work on a single battery charge. The Tan 01 color blends naturally with common wood tones for a finished, professional appearance on decking surfaces, guard rails, fascia, and trim.

Key Features

• Type 305 Stainless Steel material and finish - provides strong corrosion resistance for outdoor, deck, and dock environments where moisture exposure is a constant concern, keeping fasteners secure and structurally sound over time.
• Unique box-thread design with raised-ridge technology - greatly reduces driving torque so you drive more screws per battery charge, increasing productivity on large decking and railing projects.
• Specially designed sharp point - penetrates hard wood products and engineered deck boards with ease, eliminating the need for pre-drilling in most applications and speeding up installation.
• T25 6-lobe drive - delivers a secure, precise bit fit that results in easier driving, reduced cam-out, and extended bit life over long projects.
• Flat head with 0.335 in. head diameter - sits flush with the deck board surface for a clean, snag-free finish on decking, fascia, and trim installations.
• Tan 01 color coating - blends with natural wood tones so fastener heads remain visually unobtrusive on finished deck surfaces and trim work.
• 3 in. length in #10 screw size - provides the penetration depth needed for secure wood-to-wood fastening in standard deck board and framing applications.

Why This Product

• Built for exterior and near-water environments - Type 305 stainless steel construction resists the corrosion caused by outdoor moisture, rain, and humidity, making these screws a dependable choice for docks, boardwalks, and exposed deck framing where standard steel fasteners would fail prematurely.
• Engineered to reduce installer fatigue and battery drain - the box-thread design directly addresses one of the most common pain points in large-scale deck installation: high driving torque that kills battery life and slows progress. Fewer battery swaps means faster project completion.
• Versatile across a wide range of deck and railing applications - from deck boards and fascia to guard rail posts, infill, and post-to-framing connections, a single screw type covers multiple stages of deck construction, simplifying material selection and procurement.
• Low-profile flat head with color-matched Tan 01 coating - delivers a polished, finished appearance on visible decking surfaces without the need for additional caps or covers, ideal for both functional and aesthetically driven exterior builds.

Frequently Asked Questions

What types of wood and decking materials are these screws compatible with?

The Deck-Drive DWP Wood Screw is ideally suited for the majority of wood used in today's deck boards, including wood, engineered wood, and polymer materials. The sharp-point tip and box-thread design work together to penetrate hard wood products without pre-drilling in most cases, making them well suited for a broad range of exterior decking and trim materials.

Why does the box-thread design matter for deck installation?

The unique box-thread design with raised-ridge technology greatly reduces the driving torque required to set each fastener. In practical terms, this means less stress on your drill or impact driver battery, allowing you to drive more screws on a single charge - a significant advantage on large deck and dock projects where hundreds of fasteners are required.

Is Type 305 stainless steel appropriate for coastal or saltwater environments?

Type 305 stainless steel provides strong corrosion resistance suitable for outdoor, deck, dock, and boardwalk applications including marine environments. For seaside and directly coastal environments with heavy saltwater exposure, Simpson also offers DWP Wood SS screws in Type 316 stainless steel, which provides an elevated level of corrosion resistance for those conditions.

What bit is required to drive these screws?

These screws use a T25 6-lobe drive. The 6-lobe design provides a secure bit-to-screw fit that reduces cam-out during driving and extends overall bit life. A standard T25 (Torx-compatible) driver bit is needed for installation.
