• High-torque capability with external hex drive and 0.563" head width for secure fastening in heavy-duty applications
• Optimized wood penetration with pointed tip and 7 TPI thread pattern for smooth insertion and reduced driving force
• Industry-standard compatibility with 3/8" diameter and 3-1/2" length meeting common wood construction requirements
• Enhanced durability with 2-1/4" minimum thread length ensuring deep engagement and reliable performance

Professional Applications & Engineering Value

These black oxide steel wood screws deliver exceptional performance in demanding wood fastening applications where corrosion resistance and structural integrity are critical. The thread forming technology eliminates the need for pre-drilling in many applications while creating stronger, more permanent connections by compressing wood fibers rather than removing them. This partially threaded design provides the ideal balance between initial gripping strength and prevention of wood splitting, making them perfect for structural wood assemblies, timber construction, and heavy-duty furniture manufacturing. The external hex drive accommodates high torque applications, ensuring secure fastening in industrial settings where vibration resistance and long-term reliability are essential requirements for professional woodworking and construction projects.

Specification Summary & Compliance

Manufactured to exacting ASME B18.2.1 standards with precise dimensional accuracy, these wood screws feature a 3/8" diameter, 3-1/2" overall length, and 7 threads per inch configuration. The black oxide steel construction provides consistent performance while meeting RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for environmental safety. The right-hand threaded, partially threaded design with 2-1/4" minimum thread length ensures proper engagement depth, while the external hex drive with 0.563" head width and 1/4" head height delivers optimal torque transmission for industrial wood fastening applications.
