GRK's RSS^TM 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. The 5/16" has a shear strength of up to 1,800 lbs. The 3/8" has a shear strength of up to 2,900 lbs. 

RSS^TM 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 screw's 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.

Our round head with 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^TM screw in pre-drilled hardware like hinges and connector plates. Short lengths of the RSS^TM may also be used to install wire diamond mesh for stucco buildings.

The #30 Star Drive will deliver approximately 650 lbf of energy, eliminating the need to drill a pilot hole.

The RSS^TM screw is the only lag screw replacement of its kind.

Accreditations for independent test laboratories include:

Installation procedure for Fasteners

Use appropriate driver bit.
No pre-drilling except where wood limitations require.
DO NOT use deck cleaners which contain bleach with coated metals.
Always consult wood supplier's / manufacturer's recommendations.
Metal to wood connections: avoid damage to the coating by pre-drilling the metal.
Cedar & Redwood: For best results use PHEinox Stainless Steel. If using coated fasteners, seal wood immediately with a quality sealer to lessen the likelihood of tanic acid stains.
