Simpson Strong-Tie offers the strong-drive SD connector screw for use with our connectors. Designed to replace nails in certain products, the load-rated strong-drive SD connector 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 10 d common or 16 d common nails, respectively. In addition, the galvanized coating makes the Strong-Drive SD connector screw ideal for interior and most exterior conditions.
