The Simpson Deck-Drive DSV Wood Screw (Collated) #8 x 1-5/8 in. T25 6-Lobe Tan Quik Guard is a purpose-built fastening solution from Simpson designed specifically for preservative-treated decking applications. Its rimmed flat head with under-head nibs, high-low threaded point, and variable thread shank work together to drive cleanly into wood deck boards while accommodating the natural swelling and shrinkage of fast-growth dimensional lumber. Curved collated strips make these screws a natural match for compatible Simpson Strong-Tie Quik Drive auto-feed screw driving systems, helping crews fasten deck boards quickly and consistently across large projects.

Key Features

• Low-torque variable thread design - reduces driving effort and fatigue during large deck installations, while handling the expansion and contraction common in dimensional lumber without compromising hold strength.
• Rimmed flat head with nibs - the nibs bite into the wood surface as the head seats, allowing the screw to countersink cleanly and leave a flush, finished appearance with no raised edges.
• High-low threaded point - provides fast, accurate starts without pre-drilling, keeping installation moving efficiently across deck boards.
• Quik Guard coating - delivers corrosion resistance suited for exterior environments and certain preservative-treated wood applications, meeting the performance requirements of AC257 exposure conditions 1 and 3.
• T25 6-lobe drive - the 6-lobe interface maximizes torque transfer and reduces cam-out, maintaining consistent drive depth and a cleaner finish across every fastener.
• Curved collation strip format - engineered for use with the Simpson Strong-Tie Quik Drive PRO200SG2, PRO250G2, or Project Pro auto-feed screw driving systems, enabling rapid, repeatable fastening with minimal handling.
• Tan color finish - blends with common treated wood tones for a cleaner aesthetic on exposed deck surfaces and fascia applications.

Why This Product

• Built for treated wood without compromise - the Quik Guard coating meets AC257 exposure conditions 1 and 3, making these screws a code-compatible choice for exterior decking and preservative-treated lumber where standard fasteners may fail prematurely due to corrosion.
• Engineered to work with fast-growth lumber - the variable thread design is specifically optimized for dimensional lumber that swells and shrinks seasonally, reducing the risk of boards cupping, cracking, or loosening fasteners over time.
• Speeds up installation on larger deck projects - curved collation and compatibility with Simpson Strong-Tie Quik Drive auto-feed systems eliminate the stop-and-start of hand-loading individual screws, cutting installation time significantly on guard rail infill, fencing, and full deck surfaces.
• Delivers a cleaner finished look - the rimmed flat head with nibs countersinks flush into the board surface, and the tan color coordinates with treated wood tones, resulting in a professional appearance on visible deck and fascia applications.

Frequently Asked Questions

What auto-feed driving systems are compatible with the DSVT158S collated screws?

The DSVT158S installs with the Simpson Strong-Tie Quik Drive PRO200SG2, PRO250G2, or Project Pro auto-feed screw driving systems and their corresponding attachments. The screws feature curved collation designed specifically for use with these systems.

Are these screws suitable for use with preservative-treated lumber?

Yes. The Deck-Drive DSV Wood screw features Quik Guard coating, which provides corrosion resistance for exterior and certain preservative-treated wood applications. The screws also meet the performance requirements of AC257 exposure conditions 1 and 3.

How does the variable thread design benefit deck board installation?

The variable thread design is optimized for dimensional lumber and is specifically engineered to withstand the swelling and shrinkage that is common with fast-growth lumber, helping maintain a secure, lasting connection in wood deck boards over time.

What drive tool is required for the T25 6-lobe drive on these screws?

The DSVT158S uses a T25 6-lobe drive, which requires a T25 6-lobe (Torx-compatible) bit. This drive type provides a secure, slip-resistant engagement to help reduce cam-out during installation, especially when used with the compatible Quik Drive auto-feed systems.
