Professional Applications & Engineering Value

These 18-8 stainless steel wood screws deliver exceptional performance in demanding wood fastening applications where corrosion resistance and structural integrity are critical. The external hex drive provides superior torque transfer compared to standard drives, preventing cam-out during high-torque installation in hardwoods or pressure-treated lumber. The thread forming design creates strong, permanent threads in wood without removing material, significantly reducing the risk of loosening under vibration or load cycles. With partial threading and a pointed tip, these screws minimize wood splitting while ensuring precise alignment in decking, timber construction, and outdoor furniture assembly. The combination of 5/16"-9 thread pitch and substantial 5-1/2" length makes them ideal for heavy timber connections, structural framing, and industrial wood applications requiring reliable, long-lasting fastening solutions.

Specification Summary & Compliance

This 5/16"-9 x 5-1/2" wood screw features inch system measurements with Class 2A thread tolerance per ASME B18.2.1 specifications. The right-hand threaded design with 9 threads per inch and partial threading ensures optimal performance in wood applications. Manufacturing and material compliance includes ASME B18.2.1 standards for dimensional accuracy, RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions, and REACH (EC 1907/2006) compliance for chemical safety regulations.
