Simpson Deck-Drive DWP Wood Screw in #10 x 3" with Type 305 Stainless Steel finish is engineered by Simpson for deck, dock, and general exterior fastening applications where enhanced corrosion protection is a priority. Featuring a Tan 03 color coating, trim head profile, and T25 6-Lobe drive, this screw is purpose-built for securing the majority of wood, engineered wood, and polymer deck board materials used in today's outdoor construction. The sharp point and box-thread design work together to deliver fast, clean penetration with reduced driving effort - making it a go-to choice for professional deck builders and contractors working on boardwalks, docks, and exterior trim.

Key Features

• Type 305 Stainless Steel material and finish - provides strong corrosion resistance for exterior, deck, and dock applications exposed to moisture and the elements, extending the service life of your fastening.
• Unique box-thread design with raised-ridge technology - greatly reduces driving torque so you drive more screws per battery charge, improving productivity on large decking projects.
• Specially designed sharp point - penetrates hard wood and engineered wood products with ease, eliminating the need for pre-drilling in most standard decking scenarios.
• T25 6-Lobe drive - delivers a secure bit fit that results in easy, controlled driving and extended bit life, reducing bit cam-out and replacements on the job.
• Trim head profile with 0.335 in. head diameter - sits flush and nearly flush with the surface, producing a clean, finished appearance ideal for fascia, trim, and visible deck surfaces.
• Tan 03 color coating - blends with common tan and natural wood-tone deck boards for a low-visibility fastener appearance that complements the finished deck aesthetic.
• Compatible with wood, engineered wood, and polymer materials - offers broad versatility across the range of modern deck board products in a single screw design.

Why This Product

• Built for corrosion-prone exterior environments - Type 305 Stainless Steel construction means this screw resists rust and degradation in wet, outdoor conditions including decks, docks, and boardwalks where standard steel fasteners fail prematurely.
• Reduces installer fatigue and battery drain - the box-thread design with raised-ridge technology lowers driving torque, letting crews fasten more material on a single charge without sacrificing holding power.
• Sharp point eliminates pre-drilling on most deck boards - the purpose-designed tip penetrates hard and engineered wood directly, saving time and steps during installation of deck and exterior trim applications.
• Trim head and Tan 03 finish deliver professional results - the low-profile head and color-matched coating keep fasteners visually discreet on tan and natural-toned deck surfaces, meeting the aesthetic standards of finished exterior projects.

Frequently Asked Questions

What materials are these screws compatible with?

The Deck-Drive DWP Wood Screw is designed for use with wood, engineered wood, and polymer materials - covering the broad range of deck board products commonly used in today's exterior decking and dock construction.

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

The unique box-thread design with raised-ridge technology greatly reduces driving torque compared to standard thread forms. This means less resistance during driving, which allows installers to drive more screws on a single battery charge - a significant advantage on large decking or dock projects.

Is Type 305 Stainless Steel appropriate for all outdoor environments?

Type 305 Stainless Steel provides strong corrosion resistance suited for deck, dock, and general exterior applications where extra protection from moisture is needed. For seaside and coastal environments with direct saltwater exposure, a higher-grade stainless steel such as Type 316 is recommended.

What is the purpose of the Tan 03 color coating on these screws?

The Tan 03 color coating is applied to help the trim head blend with tan and natural-toned wood deck boards, reducing the visual impact of the fastener on finished surfaces. This is particularly useful for fascia, trim, and exposed decking where a clean, low-visibility appearance is desired.
