S-94048A404 Length 4" 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-lasting performance in outdoor or humid wood applications.
• High-torque installation capability thanks to the external hex head design, allowing for secure tightening with standard tools.
• Enhanced pull-out resistance from the thread forming tapping method, which creates strong, permanent threads in wood without pre-drilling in many cases.
• Optimized wood grip with partial threading and pointed tip, reducing wood splitting while maintaining strong holding power.
• Heavy-duty load capacity supported by 3/4" diameter and 4" length, ideal for structural wood connections and framing.
• Reliable compliance with ASME B18.2.1, ASTM A307, and SAE J429 standards, ensuring consistent quality and safety in industrial use.
• Environmental and safety assurance through RoHS 3 and REACH compliance, making them suitable for regulated projects.

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws are engineered to address common challenges in wood construction, such as corrosion from moisture and high stress loads. The hex head design provides excellent torque transfer, minimizing slippage during installation in demanding applications like timber framing, deck building, and outdoor structures. With a thread forming method and partial threading, the screws reduce the risk of wood splitting while ensuring a tight, durable fit. The right-hand thread and pointed tip facilitate easy insertion, saving time on job sites. Ideal for heavy-duty wood fastening, these screws deliver consistent performance in compliance with industry standards, enhancing project longevity and reducing maintenance needs.
