S-94048A423 Length 16" 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, ensuring long-term reliability in outdoor and high-moisture wood applications
• Enhanced torque transmission through the external hex head design, preventing cam-out and enabling secure installation with standard tools
• Optimized holding power with partial threading that provides maximum grip in wood while reducing splitting risk in dense materials
• Excellent thread-forming capability creates strong, permanent threads in wood without pre-drilling in many applications
• Heavy-duty construction with 5/8" diameter and 16" length, engineered for demanding timber and structural wood connections
• Industry-standard compliance meeting ASME B18.2.1, ASTM A307, and SAE J429 specifications for consistent quality and performance
• Environmental responsibility with full RoHS 3 and REACH compliance, ensuring safe use in regulated industrial environments

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws deliver exceptional engineering value for construction professionals and industrial woodworking applications. The 5/8" diameter and substantial 16" length provide the structural integrity needed for heavy timber construction, deck framing, and outdoor structural projects where vibration resistance and long-term stability are critical. The thread forming design creates precise, durable threads in wood substrates without compromising material integrity, while the partial threading configuration concentrates holding power where it's most effective. The external hex drive system ensures maximum torque application without stripping, making these wood screws ideal for high-stress connections in treated lumber, timber framing, and industrial wood structures exposed to environmental challenges.

Specification Summary & Compliance

These heavy-duty wood screws feature a 5/8" thread diameter with 5 threads per inch and 4" minimum thread length in a right-hand thread direction. Manufactured to Class 2A thread tolerances and compliant with ASME B18.2.1, ASTM A307, and SAE J429 standards for dimensional accuracy and mechanical properties. The products are fully certified as RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting the latest environmental regulations for industrial fasteners.
