The Simpson Deck-Drive DSV Wood Screw (Collated) - #10 x 2-1/2 in., Tan, 500-Qty is a professional-grade fastening solution built for preservative-treated wood decking applications. Featuring a curved-collated strip format, these screws are designed to work with the Simpson Quik Drive auto-feed screw driving system, delivering fast, repeatable, and consistent results across deck board installations. The variable thread design handles the natural swelling and shrinkage common with fast-growth dimensional lumber, while the Quik Guard coating provides corrosion resistance suited for exterior and certain preservative-treated wood environments - making these screws a dependable choice for wood-to-wood fastening, decking, fencing, guard rail assemblies, and railing post-to-deck framing applications.

Key Features

• Low-torque thread design - reduces driving effort during installation, allowing faster work with less fatigue over long runs of decking.
• Rimmed flat head with under-head nibs - countersinks smoothly and cleanly into wood deck boards, leaving a polished, finished appearance without surface damage.
• High-low threaded point - provides fast, confident starts with every drive, minimizing slippage and reducing the need for repositioning.
• Variable thread design optimized for dimensional lumber - engineered to accommodate the natural swelling and shrinkage of fast-growth wood, maintaining a reliable, long-lasting connection over time.
• Quik Guard coating - delivers corrosion resistance for exterior and certain preservative-treated wood applications, helping the fastener hold up in demanding outdoor conditions.
• Meets AC257 exposure conditions 1 and 3 - satisfies recognized industry performance requirements, giving contractors and builders confidence in code-sensitive installations.
• T25 6-lobe drive with included driver bit - the six-lobe interface maximizes torque transfer and reduces cam-out, and the included T25 bit means you can get to work immediately.
• Curved-collation format - compatible with the Simpson Quik Drive PRO250G2, PRO300SG2, and Project Pro auto-feed screw driving systems, enabling high-volume deck fastening with consistent depth and spacing.

Why This Product

• Purpose-built for wood decking environments - the combination of the high-low tip, under-head nibs, and variable thread geometry addresses the specific challenges of driving screws into today's fast-growth dimensional lumber, from clean countersinking to long-term holding power as wood moves seasonally.
• Corrosion resistance backed by verified performance standards - the Quik Guard coating meets the performance requirements of AC257 exposure conditions 1 and 3, making these screws a documented, reliable choice for treated-wood deck construction rather than a general-purpose fastener pressed into service.
• Designed for auto-feed productivity - the curved-collated strip format pairs directly with the Simpson Quik Drive auto-feed screw driving systems, enabling faster installation across large deck surfaces compared to hand-loading individual fasteners, without sacrificing placement accuracy or drive consistency.
• Ready to install out of the box - a T25 driver bit is included in the package, so contractors and serious DIYers have everything needed to begin fastening immediately without sourcing a separate accessory.
