Strong-Drive® SD CONNECTOR Screw 

Strong-Drive® SD CONNECTOR Screw

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 10d common or 16d common nails, respectively. In addition, the galvanized coating makes the Strong-Drive® SD Connector 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.

Key Features

  • 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.
  • Ideal for use in connector applications where more control is desired or using a hammer is inconvenient.
  • 1/4" 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
  • Patented serrated threads and sharp point make driving easier
  • Optimized heat treating for ductility and strength
  • 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
  • Mechanically galvanized coating meets ASTM B695 Class 55, is recommended for use with certain preservative-treated woods and recognized as an alternate to hot-dip galvanized in ESR-3046. It is compliant with the 2006, 2009, and 2012 International Residential Code® (2006 Section R319.3, 2009 and 2012 Section R317.3.1)
  • Connectors installed with the SD screw code listed under ICC-ES ESR-3096

    These coated fasteners possess a level of corrosion resistance that makes them suitable for use in some exterior and corrosive environments and with some preservative-treated woods. For applications in higher-exposure applications, consider type-300 series stainless-steel fasteners for superior corrosion resistance. See additional important information before selecting a fastener for a specific application.

Load Tables

Allowable Shear Loads with Steel Side Plate
  1. Allowable loads are shown at the wood load duration factor of CD = 1.00. Loads may be increased for load duration per the building code up to a CD = 1.60.
  2. Allowable withdrawal load for DF/SP is 173 lbs./in. and for SPF/HF withdrawal is 122 lbs./in.. Total withdrawal load is based on actual thread penetration into the main member.
  3. Withdrawal load for wood side member thickness of 15/32" is limited to the pull-through load of 130 lbs.
Allowable Shear Loads with Wood Side Plate
  1. Allowable loads are shown at the wood load duration factor of CD = 1.00. Loads may be increased for load duration per the building code up to a CD = 1.60.
  2. The 15/32" and 23/32" side members must be plywood or OSB with minimum equivalent specific gravities of 0.50 for DF and SP design values, and 0.42 for SPF and HF design values.
