S-94048A269 Length 4" ASME B18.2.1, ASTM A307, SAE J429 Wood Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with hot-dipped galvanized steel construction for long-lasting performance in outdoor and high-moisture environments
• Maximum torque transfer and installation efficiency through external hex drive design that prevents cam-out and allows high-tightening forces
• Superior wood holding power with partially threaded shank design that provides optimal grip and prevents wood splitting
• Enhanced thread engagement with minimum 2.667" thread length ensuring secure fastening in various wood thicknesses
• Reliable thread forming capability that creates strong, permanent threads in wood without pre-drilling in many applications
• Industry-standard compliance meeting ASME B18.2.1, ASTM A307, and SAE J429 specifications for consistent quality and performance
• Environmental regulation compliance with RoHS 3 and REACH standards for safe, sustainable manufacturing practices

Professional Applications & Engineering Value

These heavy-duty wood screws are engineered to solve critical fastening challenges in construction and timber applications. The hot-dipped galvanized steel construction provides superior corrosion protection, making them ideal for outdoor structures, decking, and fencing where moisture resistance is essential. The external hex drive design ensures maximum torque application without stripping, while the partially threaded configuration with thread forming capability creates strong, permanent connections in wood substrates. The 5/16" diameter and 4" length provide substantial holding power for structural applications, from timber framing to heavy construction projects where reliability cannot be compromised.

Specification Summary & Compliance

These wood screws feature a 5/16" thread diameter with approximately 9 threads per inch in right-hand thread direction. The partially threaded design includes a minimum 2.667" thread length with pointed tip for easy starting. Manufacturing complies with ASME B18.2.1 dimensional standards, ASTM A307 material specifications, and SAE J429 mechanical requirements. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring these fasteners meet current environmental and safety standards for industrial use.
