Features

• 【Perfectly Replace SD9112R500 with Included Screwdriver】Monknestique #9 x 1-1/2" SD connection screws can perfectly replace SD9112R500 and are fully compatible with various Strong-Tie connectors. Specifically designed to replace traditional nails, they offer superior strength and stability. They feature a 1/4-inch hex head with an integrated washer having a diameter of 0.370 inches. A hex screwdriver is included for quick and convenient installation.
• 【Three-Layer Composite Coating System Ensures Excellent Corrosion Resistance】Monknestique SD connection screws use the RUSPERT coating. The multi-coating composite system is made through a thermal fusion process, consisting of a high-density ceramic surface (waterproof and corrosion-resistant), a polymer chemical bonding layer (anti-peeling), and a zinc-rich primer (cathodic protection against rust). This process far exceeds other processes like mechanical galvanization and has passed a 480-hour salt spray test, ensuring reliability in various harsh environments (acidic, alkaline, humid, coastal areas, etc.).
• 【High-Strength Material Ensures Load-Bearing Capacity and Strength】The #9 x 1-1/2" SD connector screws are made of high-strength material and optimized through excellent heat treatment. The load-bearing capacity of a single screw far exceeds that of a standard 10d nail. They can be confidently used in construction, decks, and framing.
• 【Suitable for Indoor and Outdoor Projects】These screws are widely used in both indoor and outdoor projects, providing reliable connection solutions for projects such as fences, wooden decks, frames, and bridges. They are a reliable choice when precise operation is required or when using a hammer is not suitable.
• 【Peace-of-Mind After-Sales Service】We are committed to providing you with 100% satisfaction. If you encounter any problems during the purchase and use process, we will respond promptly.
