S-94048A414 Length 9" ASME B18.2.1, ASTM A307, SAE J429 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from hot-dipped galvanized steel coating, ensuring long-term reliability in outdoor or humid wood applications
• Enhanced holding power with partially threaded design that provides maximum grip and prevents wood splitting
• Easy installation and removal thanks to the external hex drive design that allows high torque application with standard tools
• Optimal thread engagement with 7 threads per inch and 5.333" minimum thread length for secure fastening in various wood densities
• Reduced installation effort through thread forming design that creates strong mating threads without pre-drilling in many applications
• Heavy-duty construction capability with 3/8" diameter and 9" length for demanding wood structural connections
• Industry-standard compatibility meeting ASME B18.2.1, ASTM A307, and SAE J429 specifications for reliable performance

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws deliver exceptional engineering value for construction professionals facing durability challenges in wood applications. The heavy-duty 3/8" diameter combined with 9-inch length provides substantial load-bearing capacity for structural connections in timber framing, deck construction, and outdoor furniture. The thread forming design eliminates the need for tapping operations in many scenarios, reducing installation time while creating strong, permanent connections. The external hex drive ensures secure tool engagement during high-torque installation, preventing cam-out and damage to fastener heads. With partial threading concentrating grip strength where needed most, these screws prevent wood splitting while maintaining superior pull-out resistance, making them ideal for demanding wood construction projects where vibration and environmental exposure are concerns.
