Specifications
The Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector Screw is a 1/4"-diameter structural wood screw designed for a wide range of connector, wood-to-wood, and engineered wood applications. Built for strength and speed, the SDS installs without predrilling thanks to its easy-driving Type-17 point, which reduces splitting while ensuring consistent performance.
Tested and approved in multiple structural applications, the SDS screw features a corrosion-resistant double-barrier coating for durability in standard conditions.
With a large 3/8" hex head and integrated washer, these screws deliver excellent clamping strength and are stamped with the Simpson Strong-Tie® “≠” sign and fastener length for easy inspection after installation.
