Strong-Drive® SD CONNECTOR Screw 

Strong-Drive® SD CONNECTOR Screw

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.

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 with 0.37"-dia. integrated washer reduces cam-out 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 easy.
  • 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.
  • Hex driver included.

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 2012 International Residential Code®.

Applications

  • Simpson Strong‑Tie connectors

    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

Links to load tables for connectors installed with the Strong-Drive® SD Connector Screw can be found here: Connectors Approved for Use with the Strong-Drive® SD Connector screw.

SD — Allowable Shear Loads — Steel Side Plate

  1. Loads are given for CD=1.0 and may be increased for load duration per the building code to CD=1.60.
  2. Steel side plate thickness is 33 to 100 mil (20 – 12 ga.).

SD — Allowable Shear Loads — DFL, SP, SPF, HF 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.
  3. Loads are based on installation into the side grain of the wood members with the screw axis perpendicular to the wood fibers.

SD — Allowable Withdrawal Loads — DF, SP, SPF, HF Lumber

  1. The tabulated reference withdrawal design value, W, is in pounds per inch of the thread penetration into the side grain of the main member.
  2. Tabulated reference withdrawal design value, W, must be multiplied by all applicable adjustment factors from the NDS as referenced in the IBC or IRC.
  3. Embedded thread length is that portion held in the main member including the screw tip.
  4. For connections with 15/32" thick plywood or OSB side members, reference withdrawal design values, W, must be limited by the head pull-through design value of 130 lb.
