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.

    5.0 out of 5 stars Perfect for my log cabin restoration
    Reviewed in Canada on December 2, 2024
    Verified Purchase
    Needed these to help secure the corners in a 100 year old log cabin I'm restoring at our lake property. Drive fairly easily and really tightens and holds. Better value than my local fastener supplier.

  • Crib Dock Fixer
    5.0 out of 5 stars Far easier and better than common headspikes
    Reviewed in the United States on July 29, 2019
    Verified Purchase
    After years of driving 10, 12 and 14" common Head spikes in 6 x 6 timbers for dock crib construction and repair I switched these GRK structural screws. They have held up as well as Common Spikes in side by side installations subject to crushing ice and floods. The screws do not pull out as easily, but unlike the spikes you can drive them and then back them out such as if you need to temporarily attached a timber. Also the screws go in quickly and quietly, unlike that the sledge hammer blows required for a spike. Worker productivity is much higher.
