The Simpson Deck-Drive DSV Wood Screw (Collated) - #8 x 1-5/8 in., T25 6-Lobe, Quik Guard Red, 2,000-Qty is a purpose-built collated fastener from Simpson engineered for preservative-treated decking applications. Its variable thread design is optimized to handle the swelling and shrinkage common with fast-growth dimensional lumber, while the rimmed flat head with under-head nibs drives flush for a clean, professional finish. Curved-collated for use with Simpson Quik Drive auto-feed screw driving systems, this screw delivers fast, consistent installation across wood deck boards, fascia, trim, fencing, and furniture.

Key Features

• Low-torque variable thread design - reduces strain on the driver and operator during extended deck installations, making it easier to drive screws consistently through dimensional lumber
• Rimmed flat head with under-head nibs - countersinks cleanly into wood deck boards without pre-drilling, leaving a smooth, finished surface that requires no additional touch-up
• High-low threaded point - provides fast starts and immediate thread engagement, reducing the time needed to seat each fastener and keeping the work moving efficiently
• Optimized threads for dimensional lumber - designed specifically for the grain structure and movement characteristics of modern fast-growth wood, helping maintain a secure hold over time
• Quik Guard coating - delivers corrosion resistance for exterior and certain preservative-treated wood applications, meeting AC257 exposure conditions 1 and 3 so the screws hold up in demanding outdoor environments
• T25 6-lobe drive - provides superior bit engagement and reduces cam-out compared to standard Phillips drives, resulting in cleaner drives and less bit wear during high-volume projects
• Curved collation strip design - compatible with Simpson Quik Drive PRO200SG2, PRO250G2, and Project Pro auto-feed screw driving systems, enabling hands-free, rapid fastening that significantly speeds up deck construction
• 2,000-count packaging - supplies enough screws for large-scale decking projects in a single purchase, minimizing interruptions and job-site restocking

Why This Product

• Built specifically for treated wood decking - unlike general-purpose wood screws, the DSV's variable thread design and Quik Guard coating are engineered together to address the real-world challenges of exterior decking: wood movement, corrosion from preservative treatments, and the need for a clean countersunk finish
• Proven corrosion resistance for outdoor use - the Quik Guard coating meets AC257 exposure conditions 1 and 3, giving contractors and homeowners confidence that these fasteners will perform in exterior and preservative-treated wood environments without premature corrosion
• Designed for auto-feed speed - curved-collated compatibility with Simpson Quik Drive systems means installers can drive screws at a consistent depth without stopping to reload, dramatically increasing productivity on guard rail infill, deck boards, fencing, and trim work
• Versatile across multiple applications - equally suited for wood-to-wood fastening, deck guard rail infill, fencing, furniture, and fascia and trim, making this a single fastener that covers a wide range of exterior wood construction tasks

Frequently Asked Questions

What auto-feed screw driving systems are compatible with the DSVR158S collated screws?

The DSVR158S installs with the Simpson Strong-Tie Quik Drive PRO200SG2, PRO250G2, or Project Pro auto-feed screw driving systems and their corresponding attachments. The curved collation strip design is specifically engineered for use with these systems.

What type of corrosion resistance does the Quik Guard coating provide?

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 treated decking environments.

How does the head design of the DSV screw create a finished appearance in deck boards?

The rimmed flat head features under-head nibs that allow the screw to countersink easily and cleanly into wood deck boards, providing a flush, finished appearance without requiring pre-drilling or additional surface preparation.

Why is the variable thread design important for wood decking applications?

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. This helps maintain a secure, lasting connection even as the wood moves naturally over time due to moisture and temperature changes.
