S-94048A420 Length 7" 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 and high-moisture wood applications
• High-torque installation capability through external hex drive design that prevents cam-out and ensures secure fastening
• Enhanced holding power with 4.5 threads per inch and 4.667" minimum thread length for maximum grip in wood materials
• Reduced splitting risk thanks to thread forming design that displaces material rather than removing it
• Heavy-duty construction compatibility with 7" length and 3/4" diameter suitable for demanding wood fastening projects
• Quick alignment and penetration with pointed tip design for easier starting and reduced installation time
• Reliable performance assurance meeting ASME B18.2.1, ASTM A307, and SAE J429 standards for consistent quality

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws deliver exceptional value in construction and woodworking applications where corrosion resistance and structural integrity are paramount. The external hex drive provides superior torque transmission for heavy-duty fastening in timber framing, deck construction, and outdoor structures. The thread forming design creates stronger, more secure connections in wood by compressing material rather than cutting it, significantly reducing the risk of wood splitting while improving pull-out resistance. With 4.5 threads per inch and substantial 4.667" thread engagement, these screws distribute load effectively across the connection point, making them ideal for structural applications where vibration resistance and long-term reliability are critical requirements.
