The Simpson Strong-Tie Deck-Drive DHPD Hardwood Deck Screw in 2-1/2" length is engineered specifically for fastening the hardest wood decking materials, including tropical hardwoods, dense composite boards, and pressure-treated lumber used in docks and boardwalks. Crafted from Type 305 stainless steel, this #10 screw delivers lasting corrosion resistance for exterior and marine-adjacent environments where moisture and weather exposure are constant concerns. Its paddle-style drill point and wing-counterbore design work together to drive cleanly into dense wood without splitting or predrilling, making it a practical choice for professionals and DIYers tackling hardwood deck installations.

Key Features

• Paddle-style drill point - penetrates the hardest wood and wood-related products without predrilling, dramatically reducing installation time and the risk of splitting dense boards
• Wing counterbore on the shaft - removes material ahead of the head in hard substrates, allowing the compact head to countersink flush and smoothly for a clean, finished deck surface
• Compact head design (0.270 in. diameter) - sits low-profile after countersinking to minimize surface visibility and deliver a professional, finished look on hardwood decking
• Type 305 stainless steel material and finish - resists corrosion from moisture, outdoor exposure, and the tannins found in many hardwoods, keeping fasteners secure and stain-free over time
• #2 square drive - provides positive bit engagement and reduces cam-out during installation, improving control and reducing driver wear especially in dense materials
• Driver bit included - ready to use right out of the package; replacement bit model BIT2S-2-R2 is available separately when needed

Why This Product

• Designed specifically for hardwood decking - the paddle point and shaft wings work as a system to drive into dense materials without the extra step of predrilling, saving significant labor on large deck projects
• Type 305 stainless steel construction makes this screw well-suited for dock, boardwalk, and exterior deck applications where long-term exposure to moisture and humidity would corrode standard steel fasteners
• The compact head countersinks cleanly into hard material without leaving raised edges, which matters for safety and appearance on high-traffic hardwood deck surfaces and boardwalks
• Virtually eliminates board splitting during installation - critical when working with expensive hardwood deck boards where a split plank means a costly replacement

Frequently Asked Questions

Do I need to predrill holes before installing the DHPD hardwood deck screw?

No predrilling is required. The paddle-style drill point is specifically designed to penetrate the hardest wood and wood-related products with ease, and the wings on the shaft counterbore hard material so the head can countersink cleanly - virtually eliminating splitting without a pilot hole.

What type of bit does this screw use, and is one included?

This screw uses a #2 square drive. A driver bit is included with your order. If you need a replacement bit later, the compatible model is BIT2S-2-R2.

Why is Type 305 stainless steel specified for hardwood decking applications?

Type 305 stainless steel provides enhanced corrosion resistance compared to standard steel fasteners, making it well-suited for outdoor environments including decks, docks, and boardwalks where exposure to moisture, humidity, and the natural acids and tannins in many hardwoods can degrade ordinary fasteners over time.

Is this screw appropriate for dock and boardwalk construction as well as residential decks?

Yes. The DHPD hardwood deck screw is approved for use in deck board fastening, dock construction, and boardwalk applications. Its Type 305 stainless steel construction and paddle-point design make it suitable for the dense hardwoods and demanding conditions common in these environments.
