The Strong-Drive SD Connector screw is engineered specifically to replace nails within designated Simpson Strong-Tie connectors, serving as the sole screw authorized for such applications. With its load-rated design, this screw has undergone extensive testing and approval for use across a wide range of popular Simpson Strong-Tie products. Offering greater ease and convenience in installation compared to nails in certain scenarios, the SD screw achieves single-fastener load values that exceed those of typical 10d common or 16d common nails. Additionally, its galvanized coating ensures suitability for both interior and most exterior conditions.
