Product Details

GRK's RSSâ„¢ rugged structural 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. RSSâ„¢ screws which are 3-1/8 in and longer have a six threaded CEE thread that enlarges the screw hole for the non-threaded portion of the fastener, allowing the wood to settle easily and increasing 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 RSSâ„¢ 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 RSSâ„¢ screw in pre-drilled hardware like hinges and connector plates.

Key Features

  • Recessed star drive: zero stripping, with six points of contact
  • CEE thread: enlarges hole to reduce splitting, install torque
  • W-CUT™: low torque, smoother drive, reduce splitting
  • ZIP-TIP™: no pre-drilling, faster penetration, reduce splitting
  • Washer head: for immense holding power
  • 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
