S-94048A411 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 long-lasting performance in outdoor or humid wood applications
• Enhanced driving efficiency with external hex head design providing maximum torque transfer and reduced cam-out
• Stronger thread engagement through thread forming technology that creates precise mating threads without pre-drilling
• Optimized load distribution with 3-1/2" minimum thread length ensuring secure fastening in demanding wood constructions
• Reliable industrial performance meeting ASME B18.2.1, ASTM A307, and SAE J429 standards for consistent quality
• Environmental compliance assurance with RoHS 3 and REACH compliance for safe, regulated usage
• Versatile partial threading allowing unthreaded shank section for enhanced clamping force in wood-to-wood connections

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws deliver exceptional value in heavy-duty wood construction applications where corrosion resistance and structural integrity are paramount. The thread forming design eliminates the need for pilot holes in many wood types, reducing installation time while creating stronger, vibration-resistant connections. The external hex drive system ensures maximum torque application without stripping, making them ideal for industrial framing, timber construction, and outdoor wood structures exposed to environmental elements. With their 5-1/2" length and substantial 3-1/2" thread engagement, these screws provide superior pull-out resistance in demanding applications such as deck building, timber framing, and structural wood assemblies where long-term durability is critical.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 dimensional standards with ASTM A307 material specifications and SAE J429 mechanical requirements. Features 1/4"-10 UNC thread with Class 2A tolerance, right-hand threading, and partial threading configuration. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 0.438" hex head provides optimal driving surface for standard wrench or socket applications in wood fastening scenarios.
