The Simpson Deck-Drive DSV Wood Screw - #10 x 2" in Red with T25 6-Lobe Drive is a purpose-built fastening solution designed for preservative-treated wood decking, guard rail infill, fencing, and a wide range of structural wood-to-wood connections. Featuring a rimmed flat head with under-head nibs, a high-low threaded point, and a variable thread design, this screw is engineered to countersink cleanly into today's wood deck boards while resisting the expansion and contraction common in fast-growth lumber. The Quik Guard coating delivers corrosion resistance suited to exterior and certain preservative-treated wood environments, making it a reliable choice for outdoor projects where long-term performance matters.

Key Features

• Rimmed Flat Head with Nibs - the under-head nibs allow the screw to countersink smoothly and cleanly into wood deck boards, leaving a flush, finished appearance without the need for pre-drilling in many applications.
• High-Low Threaded Point - alternating thread heights engage wood fibers quickly for fast starts, reducing the effort needed to begin driving and helping keep the screw properly aligned during installation.
• Variable Thread Design - the optimized shank thread pattern is engineered to handle the swelling and shrinkage of fast-growth and dimensional lumber, helping maintain a secure hold through seasonal wood movement.
• T25 6-Lobe Drive Type - the 6-lobe socket interface provides excellent torque transfer and reduces cam-out during driving, keeping the bit engaged even under high torque loads for more consistent results.
• Quik Guard Coating in Red - provides corrosion resistance for exterior and certain preservative-treated wood applications, while the red color blends naturally with common wood decking surfaces for a clean, unobtrusive finish.
• Compatible with Quik Drive Auto-Feed System - available in collated strips for use with the Simpson Strong-Tie Quik Drive auto-feed screw driving system, making it well-suited for high-volume decking installations where speed and consistency are priorities.
• #10 Screw Size at 2" Length - sized for fastening standard wood deck boards, providing the depth and diameter needed to hold firmly without over-penetrating thinner material.

Why This Product

• Specifically engineered for preservative-treated decking applications - the Quik Guard coating and variable thread design work together to address the two most common challenges in outdoor wood fastening: corrosion and board movement over time.
• The rimmed flat head with nibs eliminates the need for a separate countersinking step in many situations, saving installation time on deck boards, fascia, trim, and fence projects.
• Dual compatibility with both hand-drive and Quik Drive collated strip systems gives contractors and DIYers the flexibility to use the same screw whether running a high-speed auto-feed driver or a standard drill, without switching fasteners mid-project.
• Suited for a broad range of exterior woodworking tasks beyond decking - including guard rail infill, fencing, furniture, and DIY home projects - making it a versatile fastener to keep on hand for wood-to-wood connections in outdoor environments.

Frequently Asked Questions

What type of wood is this screw designed for?

The Deck-Drive DSV Wood Screw is designed specifically for preservative-treated decking applications. Its variable thread design helps manage the swelling and shrinkage common in fast-growth lumber, and the Quik Guard coating provides corrosion resistance suited to exterior and certain preservative-treated wood environments.

Does this screw require pre-drilling before installation?

The high-low threaded point with its fast-start design allows the screw to begin driving quickly into wood without pre-drilling in many standard applications. The rimmed flat head with under-head nibs also assists with countersinking cleanly into deck board surfaces for a flush finish.

Can this screw be used with an auto-feed screw driving system?

Yes. The Deck-Drive DSV is available in collated strips for use with the Simpson Strong-Tie Quik Drive auto-feed screw driving system, as well as in standard configurations for hand-drive use with a T25 6-lobe driver bit.

What driver bit is required for this screw?

This screw uses a T25 6-lobe (Torx-style) driver bit. The 6-lobe interface provides strong torque transfer and helps minimize cam-out during driving, which is especially helpful when fastening through dense or preservative-treated wood materials.
