The 5/16 in RSS Rugged Structural Screw by GRK Fasteners can be used on ledger boards, retailing walls, log, and timber framing, or anywhere a conventional lag screw would be used.

GRKs RSS 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.

RSS 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 screws drawing strength. The CEE thread also reduces the likelihood of splitting the wood and the friction on the screw shank which can result in lowering the driving torque.

The round head with a built-in shield (washer type head) has no sharp edges such as on conventional lag screws. The added shoulder (nominal diameter) underneath the washer has the ability to center the RSS screw in pre-drilled hardware like hinges and connector plates. Short lengths of the RSS may also be used to install wire diamond mesh for stucco buildings.
