SPECIAL ORDER ONLY – Call your local branch (see Location link above). Simpson Strong-Tie introduces the Strong-Drive® SD screw for use with our structural 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 SD screw exceed those of typical 10d common or 16d common nails, respectively. In addition, the galvanized coating makes the SD screw ideal for both 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.


  • Tested and approved for use in many of our best selling connectors for both interior and exterior applications
  • Ideal for use in connector applications where more control is desired or using a hammer is inconvenient
  • The single fastener load capacity of the SD9 exceeds the capacity of a 10d common nail, while the single fastener load capacity of the SD10 exceeds that of the 16d common nail
  • Specifically designed to replace nails in certain Simpson Strong-Tie connectors, and is the only screw approved for that application, the NO 9 and NO 10 SD screws replace 10d and 16d nails respectively
  • 1/4 in hex head reduces cam out for easier installation and is stamped with the Simpson Strong-Tie �?� sign and the fastener size for easy identification after installation
  • Shank is specifically designed to match the fastener holes in Simpson Strong-Tie connectors
  • Mechanically galvanized coating meets ASTM B695 Class 55, is recommended for use with certain preservative treated woods and is compliant with the 2006 and 2009 International Residential Code (2006 Section R319.3, 2009 Section R317.3.1)
  • Optimized heat treating for ductility and strength
  • Patented serrated threads and sharp point make driving easier
