From the Manufacturer

GRK RSS Rugged Structural Screw has a patented design and made of specially hardened steel to provide customers with high tensile, torque and shear strength. The sharp threads and points bite instantly into material, including hardwood, reducing the splitting effect due to smaller shanks. The GRK RSS series screws that are 3-1/8-Inch and longer have six 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. The CEE thread also reduces the friction on the screw shank which can lower the driving torque and reduce splitting. The round head with built-in washer type head shield does not have any sharp edges like conventional lag screws. The added shoulder underneath the washer has the ability to center the RSS screw in pre-drilled hardware like hinges and connector plates. The RSS screws can be used as a lag screw alternative. Some sizes available is PHEINOX Stainless Steel.

    Better than a standard lag screw. Drives considerably more easily, with less chance of over-torqueing and breaking. Received promptly.

    Reviewed in the United States on February 6, 2022

    I used four bolts to hold a sculpture onto a base. Drilled 1/4 inch pilot holes into the end grain of dogwood. If you are not familiar with working that wood, it is harder and tougher than hickory. So I was worried that the threads wouldn't be able to cut their way into the wood. Had to go in part way, then unscrew to clear chips. But they are in and should hold even if the sculpture gets knocked over. I could have never done this with standard lag bolts or rather, I would have needed pilot holes that were nearly the size of the bolts.

    I used these to hang a ledger on a 54’x16’ deck. I researched many connection options. These are awesome because the washer like heads have cutters on the back to countersink the heads. This allowed me to set joists directly over these lag screws and line my deck joists up with my house floor joists. They drive easily as well.

    These are the best screws to use when you need a lag screw. I use a bigger washer for even more holding power and I like that they don’t need to be predrilled. These do great for almost every application.
