The Simpson Deck-Drive DSV Wood Screw (Collated) is a purpose-built fastening solution from Simpson designed specifically for preservative-treated wood decking applications. Its rimmed flat head with under-head nibs and high-low threaded point allow the screw to countersink cleanly and start fast, even in the dense or resinous lumber common in today's treated deck boards. The variable thread design and optimized shank geometry help the fastener resist the seasonal swelling and shrinkage that fast-growth dimensional lumber is known for. This package includes 750 collated #10 x 2 in. screws in tan with a Quik Guard corrosion-resistant coating, along with a T25 driver bit, and is engineered for use with the Simpson Quik Drive auto-feed screw driving system - bringing speed, consistency, and reduced fatigue to large-scale deck framing and fencing projects.

Key Features

• Low-torque threads - reduce the effort and tool strain required to drive each screw, allowing crews to work faster with less fatigue over the course of a large project.
• Rimmed flat head with under-head nibs - the nibs shear cleanly into the wood surface as the screw seats, producing a flush, countersunk finish without the need for pre-drilling or additional prep work.
• High-low threaded point - provides fast, self-starting penetration so screws bite immediately without wandering, keeping installation moving at pace.
• Variable thread design optimized for dimensional lumber - engineered to handle the irregular grain and density variations of fast-growth wood, giving you a secure, consistent hold in treated deck boards.
• Quik Guard coating - provides corrosion resistance for exterior conditions and certain preservative-treated wood applications, helping fasteners hold up against moisture and chemical exposure over time.
• Meets AC257 exposure conditions 1 and 3 - independently verified performance gives contractors and homeowners confidence that these screws meet recognized standards for treated-wood decking environments.
• Curved collation strip compatible with Quik Drive auto-feed systems - designed to work with the Simpson Quik Drive PRO200SG2, PRO250G2, PRO300SG2, and Project Pro systems, enabling continuous, consistent driving without stopping to reload individual fasteners.
• T25 6-lobe drive with included driver bit - the 6-lobe interface delivers superior torque transfer and reduces cam-out, and the included T25 bit means you can start immediately without sourcing additional tooling.

Why This Product

• Built for treated wood from the ground up - the Quik Guard coating, AC257-compliant performance rating, and variable thread design all target the specific demands of preservative-treated decking, so you are not adapting a general-purpose screw to a specialized job.
• Collated format dramatically speeds up large installations - paired with a compatible Simpson Quik Drive auto-feed system, these curved-collation strips let installers drive screw after screw in a continuous rhythm, cutting down on repetitive bending, repositioning, and reloading that slows hand-drive work.
• Clean, finished results with no extra steps - the rimmed flat head with nibs countersinks flush on contact, producing a professional-looking deck surface without pre-drilling or post-installation cleanup.
• Everything needed to get started is included - a T25 driver bit is packed with every order, so there is no hunting for compatible accessories before the first screw goes in.
