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.

GRK 14235 5/16 x 6 RSS™ Rugged Structural Screws 20
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.
