Grk 12287 Rss Structural Screws, 3/8 In X 8 In, Star Drive, Steel, 50 Pk

GRK Fasteners RSS structural screws are heavy-duty fasteners engineered for demanding wood-to-wood connections in both interior and exterior applications. Made of specially hardened steel, these screws deliver exceptional tensile, torque, and shear strength, making them ideal for securing thick lumber, beams, deck posts, ledger boards, and other structural assemblies. They provide a code-approved alternative to traditional lag screws with easier installation and superior performance.

The innovative design combines sharp threads and points that bite instantly into material, including hardwood, while reducing the splitting effect. The CEE thread design (on screws 3-1/8 inches and longer) enlarges the screw hole for the non-threaded portion, allowing wood to settle and increasing drawing strength. The integrated washer head with no sharp edges distributes clamping force evenly, centers the screw in pre-drilled hardware like hinges and connector plates, and creates tight joints without gaps.

Features and Benefits

• Self-Drilling Design: Sharp point and precision-engineered threads eliminate the need for pre-drilling, enabling quick and efficient installation while reducing driving torque.
• High Strength: Specially hardened steel construction delivers exceptional tensile strength for heavy-load applications and structural wood-to-wood fastening.
• Reduced Splitting: The sharp thread design and smaller shank diameter reduce the risk of wood splitting, particularly in hardwoods and thick lumber.
• Integrated Washer Head: Built-in washer provides a larger bearing surface for maximum clamping force and prevents gaps between materials without sharp edges like conventional lag screws.
• Code Approved: Engineered and tested for structural wood-to-wood applications meeting building code requirements.
• Interior and Exterior Use: Suitable for both indoor and outdoor projects requiring reliable, weather-resistant fastening.
