Simpson Deck-Drive DWP Wood Screw in Type 305 Stainless Steel is a high-performance exterior fastener engineered for deck boards, dock construction, and general outdoor wood applications where reliable corrosion protection is essential. The #8 x 2" size features a flat head profile, a T20 6-lobe drive, and a sharp point tip designed to penetrate solid wood and engineered wood products cleanly - reducing the need for pre-drilling and keeping projects moving efficiently. Built from Type 305 stainless steel, these screws resist rust and weathering in demanding outdoor environments, making them a trusted choice for decking, boardwalk, and trim work.

Key Features

• Type 305 Stainless Steel material - delivers strong corrosion resistance for outdoor, deck, and dock applications where exposure to moisture and the elements is ongoing
• Unique box thread design with raised-ridge technology - greatly reduces driving torque so you can drive more screws on a single battery charge, boosting productivity on large deck projects
• Specially designed sharp point - penetrates hard wood and engineered wood products with ease, minimizing splitting and eliminating the need for pre-drilling in most wood deck boards
• T20 6-lobe drive - provides a secure bit-to-fastener fit that reduces cam-out, resulting in smoother driving and extended bit life on the job
• Flat head profile with 0.335 in. head diameter - sits flush with the wood surface for a clean, finished appearance on decking, fascia, and trim applications
• Compatible with wood, engineered wood, and polymer materials - offers versatile performance across the wide range of decking products used in modern construction

Why This Product

• The box thread geometry reduces driving resistance compared to standard thread profiles - meaning less strain on your drill battery and faster installation across full deck or dock projects
• Type 305 stainless steel construction is specifically suited for exterior and wet-environment applications such as decks, docks, and boardwalks, where standard steel fasteners would corrode prematurely
• The sharp point and box thread combination make this screw well-matched for the range of deck board materials in use today - from traditional softwood lumber to engineered and composite-style wood products
• The flat head design makes these screws equally useful for fascia boards and exterior trim work, giving contractors and builders a single fastener solution for multiple exterior finishing tasks

Frequently Asked Questions

What type of wood is this screw designed for?

The Deck-Drive DWP Wood Screw is ideally suited for the majority of wood used in today's deck boards, including solid wood, engineered wood, and polymer materials. Its sharp point and box thread design allow it to penetrate hard wood products with ease, making it a practical choice for a wide range of decking and exterior applications.

Why do the box threads reduce driving torque?

The raised-ridge box thread technology lowers the resistance the screw encounters as it advances into the wood. This reduced torque demand means your drill or driver expends less energy per fastener - allowing you to drive more screws on a single battery charge during large deck or dock installations.

Is Type 305 stainless steel suitable for all outdoor environments?

Type 305 stainless steel provides strong corrosion resistance for deck, dock, and general exterior applications. For seaside or coastal environments where salt air and saltwater exposure are present, a higher-grade stainless steel such as Type 316 is recommended for maximum protection.

What drive bit does this screw require?

This screw uses a T20 6-lobe drive. The 6-lobe design ensures a secure fit between the bit and the fastener head, which reduces cam-out and helps extend bit life - particularly useful when driving large quantities of screws on decking or trim projects.
