S-94048A278 Length 6" 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
• Enhanced torque transmission through the external hex head design, preventing stripping during high-torque installation
• Optimized wood penetration with pointed tip and partially threaded shank, reducing wood splitting while maintaining strong pull-out resistance
• Reliable thread engagement via thread forming method, creating secure, vibration-resistant connections in wood materials
• Heavy-duty load capacity with 6" length and 5/16" diameter, providing deep anchoring for structural wood assemblies
• Industry-standard compliance ensuring consistent quality, dimensional accuracy, and mechanical performance in construction projects
• Environmental regulation adherence meeting RoHS 3 and REACH requirements for safe, sustainable manufacturing

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws deliver exceptional performance in demanding wood construction and outdoor applications where corrosion resistance and structural integrity are paramount. The external hex drive combined with ASME B18.2.1 compliance ensures reliable installation without cam-out, while the thread forming design creates strong, permanent threads in wood substrates without pre-drilling in many applications. The partial threading configuration provides concentrated holding power at the engagement point while minimizing wood fiber disruption. Engineers specify these heavy-duty wood screws for decking, timber framing, outdoor furniture, and structural wood connections where galvanized corrosion protection extends service life in exposed environments, reducing maintenance costs and preventing premature fastener failure.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 dimensional standards with material specifications meeting ASTM A307 and SAE J429 requirements. Features 5/16" diameter with 9 threads per inch in right-hand direction and 4" minimum thread length on a 6" overall length. The hot-dipped galvanized surface treatment provides superior corrosion protection. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for hazardous substance restrictions.
