Simpson Strong-Tie #9 x 1-1/2 in. Type 316 Stainless Steel, Hex Drive, Hex Head, Strong-Drive SD Wood Screw (500-Pack)

The stainless-steel Strong-Drive SD Connector SS screw (SD SS) is specifically designed to replace nails in certain Simpson Strong-Tie stainless-steel connectors. The load-rated SD SS screw has been tested and approved for use in many popular Simpson Strong-Tie products. In certain applications screws are easier and more convenient to install than nails and the single-fastener load values achieved by the SD SS screw exceed those of typical 10d common nails. In addition, the Type 316 stainless steel provides excellent corrosion resistance appropriate for severe-exposure environments.

• Stainless steel screw resists rust in coastal environments
• Hex head drive allows fast, slip-free installation
• Ideal for exterior wood-to-wood structural connections
