Key Features

Approved Connector Fastener Built specifically for Simpson Strong-Tie connectors, this screw is approved to replace certain nails in those applications. That matters when load values and inspection compliance depend on using the right fastener in the right hole. Faster Controlled Installation The 1/4 inch hex head helps reduce cam-out and gives you better control than swinging a hammer in a tight corner. For framing repairs, retrofits, and overhead work, that saves time and aggravation. #10 x 1-1/2 in. This Simpson Strong-Tie SD10112R100 Strong-Drive SD Connector Screw uses a #10 shank, 1-1/2 inch overall length, and integrated washer head sized to fit connector holes correctly. It is made for connector fastening, not general deck screw duty.

Overview

The Simpson Strong-Tie SD10112R100 Strong-Drive SD Connector Screw is a mechanically galvanized connector screw made for fastening Simpson Strong-Tie metal connectors to wood framing members. This is a connector screw designed for replacing certain approved nails in Simpson Strong-Tie connector installations. Model Number: SD10112R100. If you need a cleaner, more controlled way to fasten hangers, ties, and similar hardware without fighting a hammer, this is the fastener you reach for.

This specific version is a #10 x 1-1/2 inch hand-drive screw with a 1/4 inch hex drive, hex head, sharp point, and 100-count package. The screw is specifically designed to replace nails in certain Simpson Strong-Tie connectors, and Simpson states it is the only screw approved for that application in those cases. That is the real reason this product matters. You are not just buying a wood screw. You are buying a connector fastener engineered around published load values, connector hole fit, and code-recognized performance.

On the job, the biggest advantage is control. Driving a screw into a framing connector is often easier than swinging a hammer, especially in corners, overhead locations, repair work, punch-list work, and retrofit situations where access is poor. The 1/4 inch hex head gives solid bit engagement, and the integrated washer head spreads the bearing surface at the connector face. That helps the fastener seat properly in the metal connector while making installation more predictable with an impact driver or drill.

The geometry is what separates this fastener from a generic construction screw. The shank is sized to match Simpson Strong-Tie connector holes, and the head is sized for connector-bearing contact. For this SD10112R100 variant, the listed dimensions include a 0.370 inch head diameter, 0.160 inch shank diameter, and 1-1/8 inch thread length. Those are not throwaway numbers. They are the details that let the screw fit the connector correctly and perform as intended instead of acting like a substitute that was never designed for the hardware.

Material and coating also matter here. The screw uses mechanically galvanized Class 55 coating, which Simpson notes meets ASTM B695 Class 55. It is recommended for use with certain preservative-treated woods and is recognized as an alternate to hot-dip galvanized in ESR-3046. That makes this screw a practical choice for many interior and exterior connector applications where corrosion resistance matters but you still need a fastener approved for the connector system.

Simpson also calls out optimized heat treating for ductility and strength. In plain terms, that means the screw is built to handle connector work without being overly brittle. The brand further states that the single-fastener load capacity of the SD10 exceeds that of a 16d common nail. For contractors and inspectors, that is the kind of detail that gives this fastener a real place in framing and connector installation instead of being just another screw on the shelf.

The included hex driver is another practical plus. It is a small detail, but it means you can get started right away without hunting for the correct driver bit. For crews doing framing hardware installation, repairs, or call-backs, that kind of ready-to-go packaging helps. The 100-piece pack size also makes sense for smaller runs, service work, or stocking a truck without committing to bulk pails.

Who should buy it? This screw makes the most sense for framers, remodelers, deck builders, general contractors, and serious DIY users installing Simpson Strong-Tie connectors in wood framing. If your work involves joist hangers, hurricane ties, framing angles, or similar connector hardware and you want a code-aware, approved fastening option with better installation control than nails, this is the right category of fastener. If you just need a general wood screw, buy a general wood screw. If you need a connector screw that matches the hardware and the application, buy this one.

Install Connectors Where a Hammer Is a Pain

This screw earns its keep when access is tight and clean control matters more than raw speed with a hammer. In connector work, being able to drive the fastener straight and seat it cleanly makes the install easier and more consistent.

• 1/4 inch hex drive helps reduce slipping during installation
• Designed for Simpson Strong-Tie connector fastening in wood framing

Made to Fit the Hardware Correctly

Generic screws are not a substitute for connector fasteners. The shank and head dimensions on this SD connector screw are built around the connector holes, so the fastener works with the hardware the way it was intended to.

• 0.370 inch head diameter with integrated washer style bearing surface
• 0.160 inch shank diameter sized for connector applications

Connector Strength Without Guesswork

This fastener is built for connector performance, not just wood penetration. Simpson states the SD10 single-fastener load capacity exceeds that of a 16d common nail, which is why this screw is a real connector solution and not a workaround.

• Optimized heat treating for ductility and strength
• Sharp point starts cleanly in wood framing members

Coating Built for Interior and Exterior Connector Work

The mechanically galvanized Class 55 coating gives this fastener a place in many exterior and treated-lumber connector applications where corrosion resistance matters. It is a better fit for this work than plain interior-only fasteners.

• Mechanically galvanized Class 55 coating meets ASTM B695 Class 55
• Recognized for use with certain preservative-treated wood applications
