The Simpson Deck-Drive DSV Wood Screw (Collated) #8 x 1-1/4 in. T25 6-Lobe Tan is a purpose-built fastening solution from Simpson designed for preservative-treated decking applications and wood-to-wood connections. Its under-head nibs and high-low threaded point make it ideally suited to be driven and countersunk into today's wood deck boards, while the variable thread shank is engineered to withstand the swelling and shrinkage common with fast-growth lumber. Packaged in curved collation strips, these screws are ready to use with the Simpson Strong-Tie Quik Drive auto-feed screw driving system for high-volume deck installations, and they are also offered in a variety of sizes to fasten fascia and trim.

Key Features

• Low-torque variable thread design - reduces driver fatigue and fastener strain during high-volume installations, keeping work moving efficiently through the full deck project.
• Rimmed flat head with nibs - countersinks cleanly and consistently into wood deck boards without overdriving, delivering a smooth, finished appearance on every fastened surface.
• High-low threaded point - provides fast starts without pre-drilling, saving time and reducing setup steps on dimensional lumber and treated decking.
• Optimized threads for dimensional lumber - engineered specifically for the fiber structure of today's wood decking, including fast-growth lumber prone to movement.
• Quik Guard coating - provides corrosion resistance for exterior and certain preservative-treated wood applications, helping fasteners hold up in demanding outdoor conditions.
• Meets AC257 exposure conditions 1 and 3 - confirms the coating's performance has been independently verified for the treated-wood environments most commonly encountered in deck construction.
• T25 6-lobe drive - offers superior bit engagement compared to standard Phillips or square drives, reducing cam-out and improving control at higher drive speeds.
• Curved collation strips compatible with the Simpson Strong-Tie Quik Drive PRO200SG2 - enables auto-feed screw driving that dramatically speeds up installation and minimizes bending and kneeling on large deck projects.

Why This Product

• Engineered for treated wood from the ground up - the Quik Guard coating, AC257-compliant corrosion resistance, and variable thread design work together to address the specific chemical and structural demands of preservative-treated decking, so installers are not settling for a general-purpose fastener in a specialized application.
• Auto-feed collation cuts installation time significantly - the curved collation format is purpose-built for the Simpson Strong-Tie Quik Drive auto-feed system, allowing crews to drive screws standing upright at a consistent depth without stopping to reload individual fasteners.
• Clean countersinking protects the finished look of the deck - the rimmed flat head with nibs seats flush without surface tear-out, making these screws a strong choice for visible decking, guard rail infill, fencing, and furniture where appearance matters alongside performance.
• Versatile across multiple wood-to-wood applications - while optimized for deck boards and preservative-treated lumber, the DSV is also suited for fascia, trim, fencing, and furniture, making a single box of fasteners useful across multiple phases of a deck or outdoor project.

Frequently Asked Questions

What coating do the Simpson DSV screws have, and are they suitable for use with treated lumber?

The Simpson Deck-Drive DSV screws feature a Quik Guard coating that provides corrosion resistance for exterior and certain preservative-treated wood applications. They also meet the performance requirements of AC257 exposure conditions 1 and 3, making them appropriate for treated decking projects.

What auto-feed tool is compatible with these collated DSV screws?

These collated DSV screws are designed to install with the Simpson Strong-Tie Quik Drive PRO200SG2 auto-feed screw driving system or attachment. The screws are packaged in curved collation strips specifically for use with this system.

Why is the rimmed flat head with nibs design beneficial for deck installations?

The rimmed flat head with nibs design countersinks easily into wood deck boards and provides a clean, finished appearance. The nibs help the screw seat flush with the decking surface without requiring pre-drilling, resulting in a professional-looking installation.

How does the variable thread design help with wood deck boards?

The variable thread design is optimized for dimensional lumber and is specifically engineered so the shank can withstand the swelling and shrinkage that is common with fast-growth lumber. Combined with the high-low threaded point for fast starts and low-torque threads, the DSV drives efficiently and securely into today's wood deck boards.
