Grk Rss #10 X 3-1/8 In Star Drive Structural Screw, 800-pack

GRK RSS structural screws are heavy-duty fasteners engineered for demanding construction, deck building, and load-bearing applications. Made of specially hardened steel, these screws deliver exceptional tensile, torque, and shear strength for both professional contractors and serious DIY builders. The sharp threads and points bite instantly into softwoods and hardwoods alike, reducing the splitting effect that can compromise structural integrity.

This #10 x 3-1/8 inch screw is an efficient alternative to traditional lag screws, eliminating the sharp edges and centering challenges of conventional designs. The washer-type head design prevents damage to materials and creates a tight seal between substrates. The star drive provides consistent engagement for reliable driving on tough applications.

Features and Benefits

• CEE Thread Technology: On screws 3-1/8 inches and longer, CEE threads enlarge the non-threaded portion of the hole, allowing wood to settle naturally and increasing drawing strength while reducing driving torque and splitting risk.
• Self-Tapping Design: Sharp threads and points allow installation directly into wood without pilot holes, saving time and labor on the job site.
• Star Drive Head: The star drive provides zero-stripping performance for professional installers on demanding applications and tough jobs.
• Washer Head with Built-In Shield: The round head with integrated washer has no sharp edges like lag screws and can center the screw in pre-drilled hardware such as hinges and connector plates.
• Hardened Steel Construction: Specially hardened steel provides outstanding strength and durability for both interior and exterior use in any environment.
• Bulk Pack Size: 800 screws per box deliver cost-effective supply for large projects, deck construction, ledger board installation, and load-bearing assemblies.
