DESIGNED FOR FASTENER TYPES Fastener Types and s Specified for Simpson Strong-Tie Connectors Many Simpson Strong-Tie connectors have been designed and tested for use with specific types and sizes of fasteners. The specified quantity, type and size of fastener must be installed in the correct holes on the connector to achieve published loads. Other factors such as fastener material and finish are also important. Incorrect fastener selection or installation can compromise connector performance and could lead to failure. Simpson Strong-Tie does not offer all of these fasteners, see page 2 for more information.

DESIGNED FOR SD Structural-Connector Screw Ideally suited for use with many Simpson Strong-Tie connectors Simpson Strong-Tie offers the Strong-Drive SD structural-connector screw for use with our 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 connectors. In certain applications screws are easier and more convenient to install than nails, and the single-fastener load values achieved by the SD9 and SD0 exceed those of typical 0d common or 6d common nails, respectively. In addition, the galvanized coating makes the SD screw ideal for interior and most exterior conditions. The SD structural-connector screw features an optimized shank which is specifically designed to be compatible 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. FEATURES: connectors for both interior and most exterior applications SD9 exceeds the capacity of a 0d common nail, while the single-fastener load capacity of the SD0 exceeds that of the 6d common nail is inconvenient is recommended for use with certain preservative-treated woods and is compliant with the 2006 International Residential Code (R9.) and the 2009 International Residential Code (R7.) 4" hex drive MATERIAL: Heat-treated carbon steel FINISH: Mechanically galvanized (ASTM Class 55) CODES: See page for Code Reference Key Chart.
