Simpson Strong-Drive SD Connector Screw - #10 x 1-1/2" by Simpson is a load-rated hex-head fastener engineered specifically to replace nails in Simpson Strong-Tie structural connectors. Unlike standard screws, this is the only screw approved for that application, delivering single-fastener load values that exceed those of typical 10d common or 16d common nails. The mechanically galvanized Class 55 coating makes it well suited for interior use and most exterior conditions, giving contractors and builders a reliable, code-friendly alternative to hand-nailing in connector installations.

Key Features

• Specifically designed to replace nails in Simpson Strong-Tie connectors - the only screw approved for this application, giving you confidence that your structural connection meets load requirements
• Load values exceed typical 10d common or 16d common nails - fewer fasteners can achieve the same or greater holding strength, reducing installation time without sacrificing performance
• Mechanically Galvanized, Class 55 coating - resists corrosion in interior and most exterior environments, including exposure to weather and treated lumber conditions
• #10 screw size with 1/4 in. hex drive head - allows use of a power driver or wrench for fast, consistent installation in tight spaces where swinging a hammer is difficult or impractical
• Sharp point tip - starts without pre-drilling, speeding up installation in wood connector applications
• 0.160 in. shank diameter with 10 TPI thread - provides a strong mechanical grip through connector plates and into structural lumber
• 1-1/8 in. thread length on a 1-1/2 in. overall length - optimized thread engagement for the connector thicknesses and lumber depths typical in Simpson Strong-Tie hardware
• Hex driver included - ready to use out of the package without sourcing additional tooling

Why This Product

• The SD connector screw is the only screw tested and approved for use in many popular Simpson Strong-Tie connectors - if compliance and load ratings matter on your job, this is the fastener you need, not a generic substitute
• Single-fastener load values exceed those of typical 10d and 16d common nails - you get stronger individual connections while using a tool that gives you greater control and precision than a hammer
• Ideal for framing situations where using a hammer is inconvenient or unsafe - the 1/4 in. hex drive lets you install with a standard impact driver or socket, making overhead and confined-space work far more manageable
• Mechanically galvanized Class 55 coating extends service life in both interior and most exterior applications - a single fastener type covers a wide range of project conditions without switching to specialty hardware

Frequently Asked Questions

Can I use a standard wood screw or deck screw instead of the SD connector screw in my Simpson Strong-Tie hardware?

No. The Strong-Drive SD connector screw is specifically designed to replace nails in certain Simpson Strong-Tie connectors and is the only screw approved for that application. Using a generic screw in place of the SD screw may not meet the load ratings required for your connector, and would not carry the tested and approved designation that the SD screw holds for Simpson Strong-Tie products.

How does the load performance of the SD connector screw compare to nails?

The single-fastener load values achieved by the SD connector screw exceed those of typical 10d common or 16d common nails. This means that in approved connector applications, each SD screw delivers a stronger individual connection than a standard common nail of those sizes.

What tool do I need to install the Simpson Strong-Drive SD connector screw?

The screw uses a 1/4 in. hex drive, and a hex driver is included with your purchase. You can use a standard impact driver, drill/driver, or socket wrench fitted with a 1/4 in. hex bit to drive the screw into place.

Is the SD connector screw suitable for exterior use?

Yes. The mechanically galvanized Class 55 coating makes the SD connector screw ideal for interior and most exterior conditions. This protective coating resists corrosion and extends the service life of the fastener in outdoor and exposed framing applications.
