Simpson Deck-Drive DWP Wood Screw in #10 x 3" with Type 305 Stainless Steel finish is engineered for reliable fastening in deck, dock, and general exterior wood applications where corrosion resistance is a priority. The Type 305 stainless steel construction provides enhanced protection against moisture and the elements, making this flat head wood screw a dependable choice for outdoor decking boards, boardwalks, and trim work. With a T25 6-Lobe drive, sharp point tip, and proprietary box thread design, this Simpson fastener delivers a clean, low-torque installation in the majority of wood and engineered wood materials used in today's deck construction.

Key Features

• Unique box thread design with raised-ridge technology - greatly reduces driving torque so you can drive more screws on a single battery charge, improving efficiency on large decking projects
• Specially designed sharp point - penetrates hard wood products with ease, reducing the need for pre-drilling and speeding up installation
• Type 305 stainless steel material and finish - delivers superior corrosion resistance in outdoor and wet environments, making it suitable for decks, docks, and exposed exterior applications
• T25 6-Lobe drive - provides a secure bit fit that results in easy driving and extended bit life, reducing bit cam-out and tool fatigue
• Flat head profile - sits flush with the decking surface for a clean, professional finish and reduced trip hazard
• Compatible with wood, engineered wood, and polymer materials - offers versatile use across the wide range of deck board products available today
• 3" length with 0.335" head diameter - sized for solid penetration and holding strength in standard decking and trim applications

Why This Product

• Built for exterior exposure - Type 305 stainless steel construction resists rust and corrosion in outdoor environments, making this screw well-suited for decking, dock, and boardwalk projects where moisture contact is ongoing
• Reduces installer fatigue on large jobs - the box thread design's lower driving torque means more screws per battery charge and less strain during high-volume deck installations
• Works with today's deck board materials - the sharp point and box thread geometry are specifically suited for the range of wood and engineered wood products commonly used in modern deck construction, reducing splitting and driving resistance
• Clean, flush surface finish - the flat head design combined with the precise 0.335" head diameter creates a smooth, professional deck surface without raised fastener heads

Frequently Asked Questions

What type of wood is this screw compatible with?

The Deck-Drive DWP Wood Screw is designed for use with wood, engineered wood, and polymer materials. Its sharp point and box thread design are ideally suited for the majority of wood types used in today's deck boards, including harder species and composite products.

What is the difference between Type 305 and Type 316 stainless steel for this screw?

This screw is made from Type 305 stainless steel, which provides strong corrosion resistance for deck, dock, and general exterior applications. Type 316 stainless steel offers higher resistance to salt and chlorides and is recommended for seaside and coastal environments where exposure to saltwater is a factor.

What bit do I need to drive this screw?

This screw uses a T25 6-Lobe drive. The 6-lobe profile provides a secure fit between the bit and the screw head, which helps prevent cam-out, makes driving easier, and extends the working life of the bit.

How does the box thread design benefit installation?

The unique box thread design incorporates raised-ridge technology that significantly reduces driving torque compared to standard thread profiles. This means less resistance during installation, which allows you to drive more screws per battery charge and reduces fatigue during large decking or dock projects.
