Strong-Drive SD10212R500 Connector Screw, #10 Thread, 2-1/2 in L, Serrated Thread, Hex Drive, Steel

The Strong-Drive® SD connector screw is specifically designed to replace nails in certain Simpson Strong-Tie® connectors and is the only screw approved for that application. 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 SD screw 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 Strong-Drive® SD connector screw features an optimized shank, specifically designed for capability 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.
