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.
Tested and approved for use in many of our best-selling connectors for both interior and exterior applications.
The single-fastener steel-side-plate load capacity of the SD9 exceeds that of the 10d common nail.
Ideal for use in tight spaces where a hammer is inconvenient.
Optimized heat-treating for ductility and strength.
