S-94048A450 Length 12" 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 long-lasting performance in outdoor and high-moisture environments
• Maximum torque transmission through external hex head design, preventing cam-out during high-torque installation
• Optimized wood fastening performance with partial threading that reduces wood splitting while maintaining superior pull-out strength
• Enhanced driving efficiency with pointed tip and thread forming design for easier penetration in dense wood materials
• Heavy-duty construction capability with 12" length and 3/4" diameter for demanding structural wood applications
• Reliable thread engagement with 4.5 TPI coarse thread pattern that provides excellent holding power in wood substrates
• Industry-standard compatibility meeting multiple specifications for guaranteed quality and interchangeability

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws deliver exceptional engineering value for heavy timber construction, deck building, and structural wood framing applications. The external hex drive system ensures maximum torque application without stripping, while the partial threading design concentrates thread engagement where it matters most, reducing wood fiber disruption and preventing material splitting. The zinc coating provides sacrificial protection against corrosion, making these screws ideal for outdoor structures, marine environments, and industrial settings where moisture exposure is a concern. With their substantial 3/4" diameter and 12" length, these fasteners offer the structural integrity required for load-bearing connections in timber construction, bridge decking, and heavy industrial wood assemblies.
