The Simpson Deck-Drive DSV Wood Screw in #10 x 2" Tan is a purpose-built fastening solution from Simpson Strong-Tie, engineered specifically for preservative-treated decking, fascia, and trim applications. Featuring a variable thread design, high-low threaded point, and Quik Guard coating, this wood screw drives cleanly into dimensional lumber and fast-growth deck boards while delivering a polished, finished appearance that blends with natural wood tones. Whether you're building a backyard deck, installing guard rail infill, or tackling DIY home projects, the DSV screw is designed to handle the expansion and contraction demands of outdoor wood construction.

Key Features

• Variable Thread Design - engineered to accommodate the swelling and shrinkage typical of fast-growth lumber, helping maintain fastener integrity over time without loosening
• High-Low Threaded Point - provides fast, clean starts that reduce splitting and allow the screw to seat quickly in wood deck boards
• Rimmed Flat Head with Nibs - the underhead nibs countersink the screw flush with the surface for a clean, finished look without pre-drilling
• Quik Guard Coating - provides corrosion resistance suited for exterior and preservative-treated wood applications, helping the fastener stand up to outdoor exposure
• Tan Color Finish - blends naturally with wood decking and fascia materials for a low-profile, aesthetically consistent result
• T25 6-Lobe Drive Type - offers excellent bit engagement and torque transfer, reducing cam-out during installation and increasing driver efficiency
• 0.330" Head Diameter - sized to provide adequate bearing surface while countersinking cleanly without surface damage
• 2" Length - suitable for fastening wood-to-wood in standard deck board thicknesses commonly used in residential decking projects

Why This Product

• Designed specifically for preservative-treated decking, the DSV screw's Quik Guard coating and corrosion-resistant finish make it a reliable choice where untreated fasteners would deteriorate under outdoor and chemical exposure conditions.
• The variable thread design addresses one of the most common problems in deck construction - wood movement. The shank handles the natural expansion and shrinkage of fast-growth lumber, reducing the risk of fastener backout or surface damage over seasonal cycles.
• The rimmed flat head with underhead nibs countersinks without pre-drilling, saving time during installation on large deck surfaces and producing a clean, professional finish across fascia and trim boards as well as field decking.
• The T25 6-lobe drive reduces slippage and cam-out during driving, making the installation process faster and less fatiguing - a practical advantage on large decking projects where hundreds of fasteners are driven per session.

Frequently Asked Questions

Is this screw suitable for use with preservative-treated lumber?

Yes. The DSV Wood Screw features a Quik Guard coating that provides corrosion resistance for exterior and preservative-treated wood applications, making it appropriate for treated deck boards, fascia, and trim used in outdoor construction.

Why does the DSV screw use a variable thread design?

The variable thread design is specifically engineered to handle the natural swelling and shrinkage that occurs in fast-growth lumber and dimensional deck boards. This helps the screw maintain its holding power over time as the wood moves through seasonal changes in moisture and temperature.

Do I need to pre-drill before driving this screw?

No pre-drilling is required in most applications. The high-low threaded point provides a fast start, and the rimmed flat head with underhead nibs is designed to countersink cleanly into wood deck boards without the need for a pilot hole.

What driver bit is needed to install this screw?

This screw uses a T25 6-lobe (Torx-style) drive, so a T25 driver bit is required for installation. The 6-lobe design maximizes bit-to-screw contact, reducing cam-out and making driving more efficient compared to standard Phillips or square-drive screws.
