S-94048A413 Length 5 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 coating for extended outdoor and high-moisture service life
• High-torque installation capability through external hex drive design, ensuring secure fastening in demanding wood applications
• Reduced splitting and improved holding power with thread forming tapping method that displaces material without removing it
• Optimized load distribution from partial threading, minimizing stress concentration in wood structures
• Enhanced grip and alignment with pointed tip design for easier starting and precise screw placement
• Reliable dimensional consistency meeting ASME B18.2.1, ASTM A307, and SAE J429 standards for interchangeability
• Environmental compliance assurance with RoHS 3 and REACH certifications for sustainable procurement

Professional Applications & Engineering Value

Engineered for heavy-duty wood construction applications, these hot-dipped galvanized steel screws provide exceptional resistance to environmental degradation in outdoor structures, marine environments, and agricultural facilities. The thread forming design creates stronger mating threads in wood substrates by compressing fibers rather than cutting them, significantly reducing the risk of wood splitting while improving pull-out resistance. With 3/8" diameter and 5-1/2" length, these hex head wood screws deliver substantial clamping force for timber framing, deck construction, and structural wood connections. The external hex drive accommodates high torque application with standard tools, ensuring reliable installation in demanding industrial settings where vibration resistance and long-term structural integrity are critical.

Specification Summary & Compliance

This 3/8" x 5-1/2" wood screw features right-hand threading with approximately 7 threads per inch and 3-1/2" minimum thread length. Manufactured to ASME B18.2.1 dimensional standards with ASTM A307 material specifications and SAE J429 mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. The hot-dipped galvanized surface treatment provides consistent corrosion protection meeting industrial requirements for exterior wood fastening applications.
