S-94048A281 Length 1 1/4" ASME B18.2.1, ASTM A307, SAE J429 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with hot-dipped galvanized steel coating for long-lasting performance in outdoor and humid environments
• Enhanced torque transmission through external hex drive design prevents stripping and enables high-tightening force applications
• Optimized wood holding power with partial threading that provides maximum grip while reducing wood splitting
• Thread forming design creates stronger mating threads in wood without pre-drilling in many applications
• Right-hand threading ensures standard installation compatibility and secure fastening in wood construction
• Heavy-duty construction with 3/8" diameter and 1-1/4" length delivers reliable performance for demanding wood applications
• Industry-standard compliance guarantees consistent quality and dimensional accuracy across all installations

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws are engineered to address common challenges in wood construction and industrial applications. The external hex drive provides exceptional torque resistance, eliminating cam-out issues that plague other drive types during high-torque installation. The partial threading design creates a mechanical advantage by concentrating threads where holding power matters most, while the unthreaded shank section reduces wood splitting in dense materials. The thread forming capability displaces wood fibers rather than cutting them, resulting in tighter thread engagement and superior pull-out resistance. Ideal for structural wood connections, deck building, timber framing, and outdoor furniture, these 3/8" diameter screws maintain their integrity even under sustained load conditions and environmental exposure.
