S-94048A227 Length 3" ASME B18.2.1, ASTM A307, SAE J429 Wood Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance from hot-dipped galvanized steel coating, ensuring long-term durability in humid or outdoor wood applications
• Superior torque transmission with external hex head design, preventing cam-out and enabling high-tightening force with standard tools
• Maximum holding power through thread forming tapping method that displaces wood fibers without cutting, creating stronger permanent connections
• Optimized thread engagement with 2" minimum thread length and 10 threads per inch, providing reliable pull-out resistance in dense wood materials
• Reduced splitting risk with partially threaded shank design that allows unthreaded portion to act as precision pilot in wood assemblies
• Quick starting and alignment with pointed tip geometry, facilitating easier installation in various wood types and applications
• Industry-standard compatibility meeting ASME B18.2.1 dimensional specifications and material requirements of ASTM A307/SAE J429

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws deliver critical performance advantages for demanding wood construction and industrial applications. The hex head design provides superior torque capability compared to traditional Phillips drives, eliminating stripping during high-tension fastening in hardwood, pressure-treated lumber, and structural timber connections. The thread forming action creates permanent, vibration-resistant joints by compressing wood fibers rather than removing material, significantly enhancing pull-out strength in decking, framing, and furniture manufacturing. With partial threading and 10 TPI coarse thread pitch, these screws prevent material splitting while ensuring rapid installation in production environments. The heavy-duty 1/4" diameter and 3" length make them ideal for joining thick wood sections in outdoor structures, pallet manufacturing, and industrial equipment where corrosion resistance and long-term reliability are paramount.
