Simpson Deck-Drive DWP Wood Screw in #7 x 3", Type 316 Stainless Steel with Tan 03 finish is engineered for demanding deck, dock, and general exterior fastening applications where superior corrosion resistance is essential. Featuring a trim head profile, T15 6-lobe drive, and sharp point with unique box-thread design, this screw drives cleanly into wood and engineered wood substrates while delivering the long-term durability needed in coastal, seaside, and high-moisture outdoor environments.

Key Features

• Type 316 stainless steel construction - provides enhanced resistance to salt, moisture, and harsh outdoor conditions, making it the right choice for seaside and coastal decking installations where standard fasteners would corrode prematurely.
• Unique box-thread design with raised-ridge technology - greatly reduces driving torque so installers can drive more screws on a single battery charge, improving efficiency and reducing tool 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 standard deck board materials and speeding up installation.
• T15 6-lobe drive - offers a secure, positive bit engagement that results in smooth, consistent driving and extended bit life, reducing bit cam-out and replacement costs over the course of a project.
• Trim head profile with 0.230" head diameter - sits low and cleanly against the surface, delivering a finished, refined appearance ideal for fascia, trim, and millwork applications.
• Tan 03 color finish - blends naturally with common deck board tones, keeping fastener heads discreet and maintaining the visual appeal of the finished deck surface.
• Compatible with wood, engineered wood, and polymer materials - gives contractors and builders flexibility across a wide range of modern deck board products without changing fastener types.

Why This Product

• Built for coastal and waterfront environments - Type 316 stainless steel offers a higher level of corrosion protection than standard stainless grades, making this screw specifically suited for docks, boardwalks, and seaside decks exposed to salt air and water.
• Reduces fatigue and speeds up large installations - the box-thread design with reduced driving torque means fewer battery recharges and less strain on the installer, a real advantage when fastening hundreds of deck boards.
• Versatile across wood and composite materials - the sharp point and box-thread geometry work across the majority of wood species and engineered materials commonly used in today's deck boards, reducing the need to stock multiple screw types.
• Finish and head design work together for a professional result - the Tan 03 coating and low-profile trim head combine to keep hardware visually minimal, whether used on decking surfaces, fascia boards, or exterior trim details.

Frequently Asked Questions

Why choose Type 316 stainless steel over standard stainless for deck screws?

Type 316 stainless steel provides a higher level of corrosion resistance than standard grades, making it particularly well suited for seaside, coastal, and waterfront environments such as docks and boardwalks where salt air and moisture exposure are ongoing concerns.

What is the benefit of the box-thread design on the DWP Wood screw?

The unique box-thread design with raised-ridge technology greatly reduces driving torque during installation. This means you can drive more screws per battery charge, which improves productivity on large decking projects and reduces physical fatigue for the installer.

What materials can this screw be used with?

The Deck-Drive DWP Wood screw is suitable for use with wood, engineered wood, and polymer materials, making it compatible with the majority of wood and composite deck board products commonly used in modern exterior decking applications.

What does the Tan 03 color coating do?

The Tan 03 finish is designed to visually blend with common deck board tones. Combined with the low-profile trim head, the coating helps fastener heads remain discreet against the surface, preserving the clean, finished appearance of decking, fascia, and exterior trim installations.
