The Simpson Strong-Drive SDS Heavy-Duty Connector Screw in 1/4 in. diameter by 2 in. length is a high-strength structural fastener engineered for demanding connector installations, wood-to-wood assemblies, and engineered wood applications. Designed for professional construction and structural framing work, this screw eliminates the need for predrilling, saving time on the job site while delivering reliable holding power in a wide range of structural fastening scenarios. The corrosion-resistant double-barrier coating makes it a dependable choice for applications where long-term durability is essential.

Key Features

• Type-17 Point - enables fast, easy driving without predrilling, reducing installation time and labor on structural connector projects
• 3/8 in. Hex Head Drive - compatible with a standard hex driver for quick, secure engagement and reduced cam-out during high-torque driving
• Double-Barrier Coating - provides corrosion resistance to help extend the service life of the fastener in demanding installation environments
• Serrated Thread Design at 10 TPI - serrated threads grip wood fibers aggressively, promoting strong holding power in solid wood and engineered lumber
• 0.235 in. Shank Diameter - delivers a robust cross-section for high-strength structural connections without over-splitting the work piece
• 1-1/4 in. Thread Length - positions thread engagement precisely for reliable fastening in connector flanges and wood substrates
• No Predrilling Required - the Type-17 point self-starts in wood, speeding up installation and reducing the number of tools needed on site

Why This Product

• Purpose-built for Simpson Strong-Tie connector installations, this screw is tested and optimized to work with structural connectors - so you can install with confidence knowing the fastener is matched to the application.
• The combination of a Type-17 point and serrated threads means no predrilling and strong wood grip, making it well suited for high-volume framing and connector work where efficiency and holding strength both matter.
• The double-barrier corrosion-resistant coating protects the fastener's integrity over time, supporting long-term structural performance in connector and wood-to-wood assemblies.
• With a hex head drive and 3/8 in. hex socket compatibility, installation is straightforward using a standard low-speed 1/2 in. drill - no specialty tools required beyond what most crews already carry.
