Product Details

GRK's RSS™ 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™ 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™ screw is an efficient lag screw alternative. Our round head with built-in shield has no sharp edges like conventional lag screws. The added shoulder underneath the washer has the ability to center the RSS™ screw in pre-drilled hardware like hinges and connector plates.

Key Features

  • Cutting pockets provide a clean hole, reduces splitting and bore with precision
  • Case hardened steel for high-tensile, torque and shear strength
  • Climatek™ coating is AC257 code approved for use in treated lumber
  • Washer head for immense holding power
