GRK's RSS (tm) screw is made of specially hardened steel to provide you with high tensile, torque and shear strength. The sharp threads and points bite instantly into the material (including hardwood), reducing the splitting effect due to smaller shanks. RSS (tm) screws that are 3-1/8 in and longer have CEE threads which enlarge the screw hole for the non-threaded portion of the fastener, allowing the wood to settle easily and increases the screw's drawing strength. The CEE thread also reduces the friction on the screw shank which can result in lowering the driving torque and the likelihood of splitting the wood. This is why the RSS (tm) screw is an efficient lag screw alternative. Our round head with built-in shield (washer type head) has no sharp edges like conventional lag screws. The added shoulder (nominal diameter) underneath the washer has the ability to center the RSS (tm) screw in pre-drilled hardware like hinges and connector plates. Easy to install lag alternative. Zero stripping recessed star drive. Cee thread for a clean finished look. W-Cut for low torque, smoother drive. ZIP-TIP for no pre-drilling, faster penetration. Washer head provides immense holding power. Cutting pockets p rovide a clean hole, reduces splitting, and bore with precision. ESR-3201 Approved for structural application. Climatek Coated: AC257 code approved for use in treated lumber. For interior/exterior use in: carrying beams, ledger boards, stair rails, deck p osts, playground equipment and other professional applications.
