Strong-Drive® SD Screw for Structural Connectors

Simpson Strong-Tie introduces the SD Strong-Drive® load-rated screw for use with our structural connectors. Designed to replace nails in certain products, the SD9 and SD10 have been designed, 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 screws exceed those of typical 10d common or 16d common nails. In addition, the galvanized coating makes the SD screw ideal for interior and most exterior conditions.

The SD screw features an optimized shank which is specifically designed to match the fastener holes in Simpson Strong-Tie connectors. The hex head virtually eliminates cam-out and helps avoid stripping of the head. The sharp point of the screw enables fast starts, and the serrated threads reduce torque for improved drivability.
