• High-Quality Material: Made from specially hardened steel, the GRK Fasteners RSS™ screw offers impressive tensile, torque, and shear strength, making it a dependable choice for heavy-duty applications.


• Innovative Thread Design: The sharp threads and points are designed to bite instantly into materials, including hardwood, minimizing the risk of splitting due to smaller shanks.


• CEE Threads: For screws that are 3-1/8 inches and longer, the CEE threads enlarge the screw hole for the non-threaded portion, allowing wood to settle easily and enhancing the screw's drawing strength.


• Reduced Friction: The CEE thread design also reduces friction on the screw shank, which lowers driving torque and decreases the likelihood of splitting the wood, making it an efficient alternative to lag screws.


• Washer Head Design: The round head with a built-in shield (washer type head) eliminates sharp edges found on conventional lag screws, providing a safer and more user-friendly experience.


• Versatile Applications: Perfect for various projects, including carrying beams, ledger boards, stair rails, deck posts, and playground equipment, making it suitable for both indoor and outdoor use.
