Professional Applications & Engineering Value

These black oxide steel wood screws deliver exceptional engineering value through their specialized thread forming design that eliminates the need for pre-drilling in many wood applications. The external hex drive system provides superior torque transmission, preventing cam-out during high-torque installation in dense hardwoods or pressure-treated lumber. The partial threading configuration allows for effective clamping force distribution while minimizing wood splitting risks. Ideal for structural wood connections, deck building, timber framing, and outdoor furniture assembly, these screws maintain their corrosion-resistant properties even in challenging environmental conditions. The combination of 5/16" diameter and 3" length provides the optimal balance between holding strength and material penetration for professional woodworking and construction projects.

Specification Summary & Compliance

Manufactured to exacting ASME B18.2.1 standards with precise thread dimensions of 0.313" diameter and 9 threads per inch. Features right-hand threading with Class 2A tolerance for reliable engagement. The black oxide surface treatment enhances corrosion resistance while maintaining dimensional accuracy. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence. The thread forming tapping method creates durable, permanent connections without compromising material integrity in wood applications.
