The Simpson Strong-Tie SD10112R500 Strong-Drive SD Connector Screw is a #10 x 1-1/2 inch connector screw packed in a box of 500 for structural connector installation in wood framing. This is a connector screw designed for fastening approved Simpson Strong-Tie connectors to wood with more control than a hammer-driven nail. Model Number SD10112R500 uses a 1/4 inch hex head and mechanically galvanized Class 55 coating for interior and most exterior applications.

What makes this screw matter is simple: it is specifically designed to replace nails in certain Simpson Strong-Tie connectors, and Simpson states it is the only screw approved for that application. For installers, that means you are not guessing whether a generic wood screw is acceptable in a joist hanger, hurricane tie, or similar connector. The #10 SD screw is intended to replace 16d nails in approved applications, and Simpson notes that the single-fastener load capacity exceeds that of a 16d common nail.

The design is purpose-built for connector work, not general deck screw duty. The shank is sized to match fastener holes in Simpson Strong-Tie connectors, which helps the screw seat properly in the hardware instead of slopping around in oversized holes. The 0.370 inch integrated washer under the hex head spreads the bearing surface and helps the head sit correctly against the connector face. The head is also stamped for easier identification after installation, which is useful when inspection or follow-up work matters.

On the tool side, the 1/4 inch hex drive is the practical choice for this kind of fastening. It gives you better engagement than a recess-style head when you are reaching into tight framing corners, fastening overhead, or working around installed hardware where bit slip wastes time. Simpson also includes a hex driver, so the box is ready to go for installers using a drill or impact driver with a standard hex setup.

Material and finish are a big part of why this fastener belongs in connector work. The screw uses optimized heat treating for ductility and strength, which matters because connector screws need to handle load without becoming brittle. The mechanically galvanized Class 55 coating is recognized for use in many interior and exterior applications and is recommended for certain preservative-treated woods. If your job calls for approved connector fastening in treated framing or outdoor structures, this coating is part of the reason these screws are commonly specified.

In real jobsite use, this style of connector screw shines when access is limited. If you are working between joists, near roof lines, in retrofit framing, or anywhere a hammer swing is awkward, these are faster and more controlled than driving nails by hand. They are also a good fit for contractors and serious DIY users who want approved hardware installation without the hassle of nail placement in cramped spots.

Compatibility is straightforward. This screw is made for Simpson Strong-Tie connectors and should be used where that connector schedule allows the SD connector screw as a replacement fastener. It is not a catch-all substitute for every structural fastener. If you are following connector-specific fastening requirements, this is the right type of screw to keep on hand.

If you build decks, frame additions, install hangers and ties, or handle repair work where existing framing limits access, this pack size makes sense. The Simpson Strong-Tie SD10112R500 Strong-Drive SD Connector Screw is best for carpenters, remodelers, deck builders, and code-conscious DIY users who need approved connector fastening, not just any wood screw that happens to fit the hole.
