Simpson Deck-Drive DWP Wood Screw in Type 305 Stainless Steel is engineered for deck, dock, and general exterior wood fastening applications where reliable corrosion protection is essential. Featuring a trim head profile, sharp point, and unique box thread design, this #7 x 2" screw from Simpson drives smoothly into the majority of wood used in modern deck boards - reducing effort while delivering a clean, low-profile finish ideal for fascia and trim work. The Type 305 stainless steel construction provides durable resistance to rust and weathering in outdoor environments, making it a dependable choice for boardwalks, exterior millwork, and structural decking projects.

Key Features

• Type 305 Stainless Steel material - provides strong corrosion resistance for exterior and outdoor applications, protecting the fastener's integrity over time in wet and humid conditions
• Unique box thread design with raised-ridge technology - greatly reduces driving torque so you can drive more screws on a single battery charge, increasing efficiency on the job
• Specially designed sharp point - penetrates hard wood products with ease, eliminating the need for pre-drilling in most deck board materials and speeding up installation
• T15 6-lobe drive - offers a secure bit fit that reduces cam-out, resulting in easier driving and longer bit life over the course of a project
• Trim head with 0.230" head diameter - sits low and discretely against the wood surface, making it well suited for fascia boards, trim, and finish applications where aesthetics matter
• Compatible with wood, engineered wood, and polymer materials - gives installers flexibility across a wide range of deck board and trim products commonly used today

Why This Product

• Built for exterior exposure - Type 305 stainless steel construction holds up against moisture, rain, and outdoor weathering conditions encountered on decks, docks, and boardwalks without the need for additional coatings
• Trim head keeps surfaces clean - the low-profile 0.230" trim head is designed specifically for fascia and finish trim applications where a flush, unobtrusive fastener appearance is required
• Reduced torque means more screws per charge - the box thread with raised-ridge technology lowers driving resistance, which translates directly to less battery consumption and faster completion of large decking installations
• Sharp point works in hard woods - the specially engineered point is designed to penetrate hardwood deck boards without splitting or pre-drilling, making this screw a practical choice for dense and composite wood decking materials

Frequently Asked Questions

What type of wood materials is this screw compatible with?

This Deck-Drive DWP Wood Screw is designed to work with wood, engineered wood, and polymer materials, making it suitable for the majority of deck boards used in today's exterior construction projects.

Why does the box thread design matter for battery-powered tools?

The unique box thread with raised-ridge technology greatly reduces driving torque during installation. Lower torque means less power is consumed per screw, allowing you to drive more fasteners on a single battery charge - a meaningful advantage during large decking or dock projects.

Is the trim head profile suitable for visible exterior applications?

Yes. The trim head with a 0.230" head diameter is specifically designed to sit low and neatly against the wood surface, making it a strong choice for fascia boards, exterior trim, and finishing applications where a clean, low-profile look is important.

What drive bit does this screw require?

This screw uses a T15 6-lobe drive, which provides a secure bit-to-screw fit. This reduces the risk of cam-out during driving and extends the usable life of the bit compared to standard drive styles.
