The Simpson Deck-Drive DWP Wood SS Screw (Collated) - #10 x 3 in. T25 6-Lobe Type 305 Stainless Steel is a purpose-built fastening solution from Simpson designed for deck boards, dock construction, and general exterior applications where reliable corrosion protection is essential. Its collated format pairs with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system, making it a practical choice for high-volume exterior wood fastening projects including fascia and trim work.

Key Features

• Flat head profile - sits flush with the surface for a clean, finished look on deck boards and exterior wood applications
• Unique "box" thread design with raised-ridge technology - greatly reduces driving torque so screws drive faster with less effort and less wear on the tool
• Specially designed sharp point - penetrates hard wood products with ease, eliminating the need for pre-drilling in most applications
• T25 6-lobe drive - helps prevent driver-bit cam-out while driving easier and extending bit life, reducing downtime and replacement costs
• Type 305 stainless steel material and finish - delivers long-lasting durability and strong corrosion resistance suited for exposed outdoor environments including docks and coastal decking
• Curved collation strip - engineered specifically for compatibility with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed system, keeping installation efficient and consistent
• Three T25 6-lobe driver bits included - provides everything needed to get started right away, with replacement bit BITTX25 available separately

Why This Product

• Built for exterior wood fastening where corrosion protection matters - Type 305 stainless steel construction makes these screws a dependable choice for decks, docks, boardwalks, and other outdoor applications exposed to moisture and the elements
• Engineered to drive faster and smarter - the combination of a sharp point that penetrates hard wood with ease and a box thread design that reduces driving torque means less resistance, less fatigue, and more consistent results across a full installation
• Collated format maximizes jobsite efficiency - the curved collation strip is designed to work directly with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed system, cutting down on manual loading time and keeping work moving on larger decking and dock projects
• Driver-bit cam-out is a non-issue - the T25 6-lobe drive geometry maintains secure bit engagement throughout driving, extending bit life and reducing the small interruptions that slow down a project

Frequently Asked Questions

What type of stainless steel are these screws made from, and why does it matter for exterior use?

These screws are made from Type 305 stainless steel, which provides long-lasting durability and strong corrosion resistance for deck, dock, and general exterior applications where extra corrosion protection is needed.

What tool is required to install these collated screws?

These screws install with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system or attachment. Their curved collation strip is specifically designed for compatibility with this system.

What makes the box thread design beneficial for deck installations?

The unique "box" thread design with raised-ridge technology greatly reduces driving torque, making the screw easier to drive into wood while reducing wear on the driver bit and the installer.

How does the 6-lobe drive improve performance compared to a standard drive type?

The T25 6-lobe drive helps prevent driver-bit cam-out while driving easier and extending bit life. Three T25 6-lobe driver bits are included with each 1,000-count package, and replacement bits (BITTX25) are available separately.
