The SIMPSON STRONG-TIE SD9212R100-R is a Strong-Drive hex head structural connector screw engineered for use with Simpson Strong-Tie connectors and general structural fastening applications. The 2.5-inch screw features a 1/4-inch hex drive head that virtually eliminates cam-out and resists stripping during installation. Patented serrated threads reduce driving torque for improved driveability, while the sharp point enables fast, clean starts. A mechanically galvanized coating provides corrosion resistance suitable for interior and most exterior applications. This box contains 100 screws and includes a compatible driver bit.
These structural screws are designed for use in residential and light commercial construction where Simpson Strong-Tie connectors, hangers, and structural hardware are installed. The optimized shank geometry is specifically sized to fit the fastener holes found in Simpson Strong-Tie connector plates. Typical applications include joist hangers, post bases, tension ties, and other structural connector installations. The mechanically galvanized coating makes them suitable for most exterior exposure conditions where pressure-treated lumber connections are used.
Designed for use with Simpson Strong-Tie structural connectors and hardware where an SD-series structural screw is specified. Suitable for interior and most exterior structural fastening applications.
Installation is typically performed by carpenters, framers, or structural contractors following applicable building codes. Verify that the correct screw size and quantity per connector is specified on the structural drawings or connector manufacturer load tables before driving fasteners. Use the included hex driver bit and a variable-speed drill or impact driver set to an appropriate clutch setting to avoid overdriving. Do not substitute standard wood screws for structural connector screws where a rated fastener is required by the connector specification.
