Simpson Strong-Tie Strong-Drive SD CONNECTOR Screw 9 x 1-1/2 inch 1/4-Hex Drive, Mech. Galv.

These Simpson Strong-Tie Strong-Drive® SD connectors screws are constructed to replace nails in applications where screws may offer better performance and convenience. The steel structural screws have a galvanized coating that makes them ideal for interior and exterior use. They exceed typical single-fastener load values, and have a hex head with washer that prevents cam-out and head stripping. With their sharp point and serrated thread, the structural screws deliver fast starts and reduce torque for easy installation.
