GRK Fasteners RSS3812BP 3/8" x 12" Blister-Pak RSS Rugged Structural Screw (2/Pack)
Speedy Lag Bolt Alternative with Immense Drawing Power
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" 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 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.
Ourround 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 screw in pre-drilled hardware like hinges and connector plates.
