S-94048A266 Length 3 1/2" ASME B18.2.1, ASTM A307, SAE J429 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with hot-dipped galvanized steel construction, ideal for outdoor and high-moisture wood applications
• High-torque installation capability thanks to the external hex head design, allowing for secure tightening with standard tools
• Enhanced pull-out resistance from thread forming technology that creates strong, permanent threads in wood materials
• Optimized wood penetration with a pointed tip and partial threading for reduced splitting and faster driving
• Heavy-duty load capacity supported by 5/16" diameter and 3-1/2" length, suitable for structural and framing projects
• Reliable industrial compliance meeting ASME B18.2.1, ASTM A307, and SAE J429 standards for consistent quality and safety
• Environmental regulation adherence with RoHS 3 and REACH compliance, ensuring safe and sustainable usage

Professional Applications & Engineering Value

These hot-dipped galvanized steel hex head wood screws are engineered to address common challenges in wood construction, such as fastener corrosion and joint failure. The thread forming design minimizes wood splitting by displacing material rather than cutting it, providing superior holding power in both softwood and hardwood. With a partial threading configuration, the screw ensures that the unthreaded shank bears against the top material for clamping force, while the threaded section anchors securely in the base wood. This makes them ideal for deck building, timber framing, and outdoor furniture assembly, where exposure to weather demands the corrosion protection of a thick hot-dipped galvanized coating. The external hex drive allows for high-torque application with impact drivers, reducing installation time and improving worksite efficiency.

Specification Summary & Compliance

This product features a 5/16" diameter with 9 threads per inch and a minimum thread length of 2.333", manufactured to ASME B18.2.1, ASTM A307, and SAE J429 specifications for dimensional accuracy and mechanical properties. The screws are partially threaded with a right-hand thread direction and comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they are free of restricted hazardous substances and safe for industrial use.
