## Features

- NAIL REPLACEMENT: The Strong-Drive SD Connector #9 x 2-1/2 inch screw is specifically designed to replace nails in certain Simpson Strong-Tie connectors and is the only screw tested and approved for that application. The single-fastener load capacity of the #9 SD exceeds the capacity of a 10d common nail.
- Type 316 Stainless Steel: The Strong-Drive SD Connector screw is made from Type 316 stainless steel that provides superior corrosion resistance for long-lasting durability. This finish withstands harsh conditions, making it ideal for both interior and most exterior applications where protection against rust is essential.
- EASY IDENTIFICATION: Designed for quick and easy use, the SD Connector screw includes a 1/4" hex head with a 0.370"-diameter integrated washer, stamped with the Simpson Strong-Tie sign and fastener size. This design simplifies installation and helps you quickly identify the correct screw post installation.
- ENGINEERED FOR DURABILITY: The shank of the SD Connector screw is specifically designed to fit precisely into fastener holes in Simpson Strong-Tie connectors. Enhanced with optimized heat treating, the screw offers improved ductility and strength, delivering reliable performance in demanding applications.
- SIMPSON STRONG-TIE RELIABILITY: At Simpson Strong-Tie, our mission is to provide solutions that help people design and build safer, stronger structures. As a pioneer in the building industry, we have an unmatched passion for problem solving through skillful engineering and thoughtful innovation.
