S-94048A392 Length 7" ASME B18.2.1, ASTM A307, SAE J429 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with hot-dipped galvanized steel coating, ensuring long-lasting performance in outdoor and high-moisture wood applications
• Enhanced torque transmission through the external hex drive design, allowing for secure installation with standard tools and reducing slippage
• Maximum holding power achieved with thread forming tapping, which creates strong, permanent threads in wood without pre-drilling in many cases
• Optimized load distribution due to the partially threaded shank, minimizing wood splitting while providing excellent pull-out resistance
• Heavy-duty construction with 5/8" diameter and 7" length, designed for demanding wood framing, decking, and structural applications
• Reliable compliance with industry standards including ASME B18.2.1, ASTM A307, and SAE J429, ensuring consistent quality and performance
• Environmental responsibility with RoHS 3 and REACH compliance, meeting strict regulatory requirements for industrial use

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws deliver exceptional engineering value for heavy-duty wood construction projects where corrosion resistance and structural integrity are paramount. The external hex drive configuration provides superior torque transmission compared to standard drives, preventing cam-out during high-torque installation in hardwoods and engineered lumber. The thread forming design creates compressive forces within the wood fiber, resulting in significantly higher pull-out strength than conventional cutting threads. This makes them ideal for deck framing, timber construction, and outdoor structures where vibration resistance and long-term reliability are critical. The partially threaded configuration concentrates holding power at the engagement point while reducing the risk of wood splitting in dense materials. With their right-hand threading and pointed tip, these screws offer quick starts and smooth driving in various wood types, from pressure-treated lumber to composite materials.

Specification Summary & Compliance

These 5/8" x 7" wood screws feature precise inch system measurements with a thread diameter of 0.625" and approximately 5 threads per inch. The partially threaded design provides a minimum thread length of 4.667" on the 7" overall length. Manufacturing and quality control adhere to ASME B18.21, ASTM A307, and SAE J429 standards for dimensional accuracy and mechanical properties. The products are fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting the latest environmental regulations for industrial fasteners.
