Strong-Drive SD Structural-Connector Screw

The Strong-Drive SD Structural-Connector screw is specifically designed for use with Simpson Strong-Tie® connectors

Designed to replace nails in certain products, the load-rated SD 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 SD9 and SD10 exceed those of typical 10d common or 16d common nails, respectively. In addition, the galvanized coating makes the SD screw ideal for interior and most exterior conditions.

The SD structural-connector screw features an optimized shank which is specifically designed to be compatible with the fastener holes in Simpson Strong-Tie connectors. The hex head virtually eliminates cam-out and helps avoid stripping of the head during installation. The sharp point of the screw enables fast starts, and the patented serrated threads reduce torque for improved drivability
Specifically designed to replace nails in certain Simpson Strong-Tie®
connectors, and is the only screw approved for that application. The #9 and #10 SD screws replace 10d and 16d nails respectively.
Tested and approved for use in many of our best-selling connectors for both interior and most exterior applications.*
