S-94048A344 Length 4 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, ideal for outdoor and high-moisture wood applications.
• High-torque installation capability thanks to the external hex head design, ensuring secure fastening without stripping.
• Enhanced holding power in wood through thread forming technology, which reduces splitting and provides reliable grip.
• Optimized thread engagement with 6 threads per inch and a 3-inch minimum thread length for maximum pull-out resistance.
• Versatile partial threading allows for precise clamping force control and reduced wood surface damage.
• Heavy-duty construction with a 1/2" diameter and 4-1/2" length, engineered for demanding structural wood fastening.
• Compliance with industry standards ensures consistent quality and reliability across professional projects.

Professional Applications & Engineering Value

These hot-dipped galvanized steel hex head wood screws are engineered to address common challenges in wood construction, such as corrosion in outdoor settings and the need for high-strength connections. The thread forming design displaces wood fibers without pre-drilling in many cases, minimizing splitting while creating strong, vibration-resistant joints. With a 1/2" diameter and 4-1/2" length, they provide exceptional load-bearing capacity for heavy timber framing, decking, and structural applications. The external hex drive enables efficient installation with standard tools, reducing labor time and ensuring consistent torque application. Ideal for contractors and engineers, these screws deliver long-term performance in environments exposed to weather, moisture, and mechanical stress, making them a reliable choice for industrial wood fastening.
