Simpson SD Connector Screws have been load-rated, tested, and approved for use in many popular Simpson-Strong Tie products. They are easier and more convenient to install than nails and the single-fastener load values exceed those of typical 10d common or 16d common nails. SD connector screws feature a galvanized coating that is suitable for interior and most exterior environments.
