The Simpson Deck-Drive DSV Wood Screw (Collated) #10 x 3 in. T25 6-Lobe Tan is a purpose-built fastening solution from Simpson engineered specifically for preservative-treated wood decking applications. Featuring a rimmed flat head with under-head nibs, a high-low threaded point for fast starts, and a variable thread design that accommodates the natural swelling and shrinkage of fast-growth lumber, these collated screws are designed for use with the Simpson Strong-Tie Quik Drive auto-feed screw driving system to deliver consistent, professional results on wood deck boards, fascia, trim, docks, boardwalks, and railing assemblies.

Key Features

• Low-torque threads - reduce driver strain and fatigue during high-volume installation, keeping work moving efficiently across large decking projects
• Rimmed flat head with nibs - countersinks cleanly into wood deck boards without pre-drilling, leaving a smooth, finished surface appearance
• High-low threaded point - bites into wood quickly for fast starts, reducing skipping and improving placement accuracy on every drive
• Variable thread design - engineered to handle the swelling and shrinkage common in fast-growth dimensional lumber, maintaining a secure connection over time
• Quik Guard coating - provides corrosion resistance for exterior environments and certain preservative-treated wood applications, helping fasteners hold up against the elements
• Meets AC257 exposure conditions 1 and 3 - confirms suitability for outdoor decking environments where performance under exposure is a code or project requirement
• T25 6-lobe drive - delivers reliable torque transfer and reduces cam-out compared to standard drive types, protecting both the fastener and the driving bit
• Curved collation strip - compatible with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed system, enabling rapid, consistent screw placement without bending over

Why This Product

• Designed for wood decking from the ground up - the combination of under-head nibs, a fast-start tip, and optimized threads makes these screws specifically suited to installing wood deck boards cleanly and securely, not adapted from a general-purpose fastener
• Built to handle real lumber behavior - the variable thread design addresses the swelling and shrinkage common in fast-growth lumber, helping deck boards stay fastened through seasonal changes without the fastener working loose
• Corrosion resistance verified for treated wood - Quik Guard coating combined with AC257 exposure condition compliance gives builders and homeowners confidence that these screws will perform in exterior conditions and alongside preservative-treated materials
• Collated format speeds up large installations - curved collation strips paired with the Simpson Strong-Tie Quik Drive auto-feed system allow continuous driving without stopping to load individual screws, making this a practical choice for decks, docks, boardwalks, and railing projects

Frequently Asked Questions

What coating do these screws have, and are they suitable for exterior use?

These screws feature Quik Guard coating, which 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 well suited for outdoor decking environments.

What tool is required to drive these collated screws?

These collated DSV screws are designed to be installed with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system or attachment. The curved collation strip is specifically engineered for compatibility with this system.

Why is the variable thread design important for deck board applications?

The variable thread design allows the shank to withstand the swelling and shrinkage that is common with fast-growth lumber, helping to maintain a secure and stable connection in wood deck boards over time as the material naturally expands and contracts.

How does the head design contribute to a finished appearance?

The rimmed flat head with nibs is engineered to countersink easily and smoothly into wood deck boards, resulting in a clean, flush, finished appearance at the surface. The tan color is also designed to blend with most natural wood tones for an aesthetically consistent result.
