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.

    Needed them, bought them, used them. They arrived for the deck build.. they are genuine GRK, they drove easily with included bit, cost was ok-ish. It saved driving around to multiple stores on,y to find out they are not in stock etc….

    Used all 5 boxes, have a good impact driver and strong wrists for driving more than 1 box, but they are fantastic to use ..

    5.0 out of 5 stars No more splits when driving screws in SPF lumber
    Reviewed in Canada on October 16, 2023
    Verified Purchase
    For years, I would have to pre-drill holes when I was building frames because the screws were too close to the end of the lumber that I was using and the lumber would always split up. I didn’t drill a hole now with these GRK screws with their drill tipped ends I can now just drive into the wood and unlike deck screws, if the screws are too long and the screw goes past the threads the GRK has a spiral bead near the head which permits easy extraction.

    Great Product
    One small complaint lags don't pull in the timbers as stated.
    You need to use clamps to st timbers then set the screws.
    You can attempt to use them with just drilling them in. However we you drive them in without the clamps you get tear out between the two and stops the screws from pulling the timbers tight.
    Adds an extra step.

    5.0 out of 5 stars These guys grip like none other - good-bye lag screws!!
    Reviewed in the United States on July 20, 2019
    Verified Purchase
    For installing a ledger board on a deck, these screws are so superior to lag screws, there is no comparison. We needed to attach over a stucco wall and all the was needed was a small 5/6" hole punched through the stucco, way easier than a big 1/2" one. These screws drive easily, cut their own threads and have so much gripping power, you have to be careful how fast/deep you drive them cuz they will crush your ledger board. Great buy on fantastic screws

    I used these to reinforce my deck framing with pressure treated 4x4s in a Y configuration on each 4x6 post. No stripping at all, pulled the boards together tightly. No complaints at all.
