The Simpson Deck-Drive DSV Wood Screw (Collated) #10 x 2-1/2 in. T25 6-Lobe Gray Quik Guard 1000-Qty is a professional-grade fastening solution from Simpson engineered for preservative-treated wood decking applications. Its rimmed flat head with nibs and high-low threaded point work together to drive and countersink cleanly into wood deck boards, while the variable thread design helps the shank handle the swelling and shrinkage common in fast-growth dimensional lumber. Supplied in curved collated strips, this package is built for high-volume deck installations using the Simpson Strong-Tie Quik Drive auto-feed screw driving system.

Key Features

• Low-torque variable thread design - reduces driving effort and fatigue during high-volume decking work, keeping productivity high across a full job.
• Rimmed flat head with nibs - the nibs cut into the wood surface as the screw seats, allowing the head to countersink cleanly without pre-drilling and leaving a finished, professional appearance.
• High-low threaded point - delivers fast, accurate starts that cut into wood quickly and minimize the risk of slipping or misalignment before the screw engages.
• Optimized threads for dimensional lumber - thread geometry is designed specifically to accommodate the expansion and contraction patterns of fast-growth wood, helping maintain long-term holding power in deck boards.
• Quik Guard coating - provides corrosion resistance suited to exterior conditions and certain preservative-treated wood applications, meeting AC257 exposure conditions 1 and 3 performance requirements.
• T25 6-Lobe drive - reduces cam-out during driving, giving the installer better bit engagement and more consistent screw seating across repeated fastening cycles.
• Curved collation strip format - compatible with the Simpson Strong-Tie Quik Drive PRO250G2, PRO300SG2, and Project Pro auto-feed screw driving systems, enabling continuous driving without stopping to reload individual fasteners.

Why This Product

• Purpose-built for treated wood decking - the Quik Guard coating meets AC257 exposure conditions 1 and 3, making these screws a dependable choice for exterior deck boards and preservative-treated lumber where corrosion resistance is a real concern, not an afterthought.
• Cleaner results with less prep work - the rimmed flat head with nibs countersinks directly into wood deck boards without requiring pre-drilling, saving time per fastener and producing a consistent, finished look across an entire deck surface.
• Designed to work with lumber that moves - the variable thread design addresses the swelling and shrinkage behavior of fast-growth dimensional lumber, helping fasteners maintain their grip as wood expands and contracts through seasonal changes.
• Built for auto-feed installation - curved collated strips integrate directly with the Simpson Strong-Tie Quik Drive PRO250G2, PRO300SG2, and Project Pro systems, turning a repetitive fastening task into a faster, more controlled workflow on large decking projects.

Frequently Asked Questions

What type of decking applications are the Simpson DSV Wood Screws designed for?

The Deck-Drive DSV Wood Screw is specifically designed as a fastening solution for preservative-treated decking applications. Its under-head nibs and high-low threaded point make it ideally suited to be driven and countersunk into wood deck boards. The variable thread design also helps the shank withstand the swelling and shrinkage common with fast-growth lumber.

What auto-feed screw driving systems are compatible with these collated DSV screws?

These collated DSV screws are compatible with the Simpson Strong-Tie Quik Drive PRO250G2, PRO300SG2, and Project Pro auto-feed screw driving systems and attachments. The curved collation type is engineered specifically for use in the Simpson Strong-Tie Quik Drive auto-feed screw driving system.

What corrosion resistance does the Quik Guard coating provide, and does it meet any industry standards?

The Quik Guard coating provides corrosion resistance for exterior and certain preservative-treated wood applications. These screws meet the performance requirements of AC257 exposure conditions 1 and 3, making them suitable for demanding outdoor decking environments.

What drive type do the Simpson DSVG212S screws use, and why does it matter?

The Simpson DSVG212S uses a T25 6-lobe drive, which provides secure bit engagement during installation. Combined with low-torque threads, the 6-lobe design helps reduce cam-out and enables efficient driving, making it well-suited for high-volume decking work with an auto-feed driving system.
