S-94048A233 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 construction, ideal for outdoor and high-moisture wood applications
• Enhanced installation efficiency through external hex drive design, allowing for high-torque application with standard tools
• Optimized holding power with thread forming tapping method that creates strong, permanent threads in wood materials
• Reduced splitting risk with partially threaded shank design that minimizes stress concentration in wood structures
• Reliable dimensional consistency meeting ASME B18.2.1 specifications for precise fit and predictable performance
• Extended service life through ASTM A307 grade steel construction, ensuring durability under heavy loads
• Environmental compliance assurance with RoHS 3 and REACH compliance for safe use in regulated industries

Professional Applications & Engineering Value

These 1/4"-10 wood screws deliver exceptional engineering value for construction and industrial wood applications where corrosion resistance and structural integrity are paramount. The hot-dipped galvanized steel construction provides a thick, durable zinc coating that withstands environmental exposure, making them ideal for outdoor structures, decking, and framing applications. The thread forming design creates precise, strong threads in wood without pre-drilling in many cases, reducing installation time while maintaining superior pull-out resistance. With 4" length and partial threading, these fasteners offer optimal clamping force distribution, preventing wood splitting in critical joints. The external hex drive configuration ensures reliable torque transmission for high-strength connections in heavy timber construction, industrial pallets, and structural wood assemblies where vibration resistance and long-term reliability are essential.
