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 Get a grip!
Verified PurchaseHow refreshing to have a screw that you tighten properly using a torx bit.
Head of GRK screw is a nice halfway point in size between a more bulky bolt head and a more miniscule Phillips head which may require a washer.
- Super NovaReviewed in the United States on October 10, 2015
5.0 out of 5 stars Most Impressive Screw I've ever used
Verified PurchaseAt first glance this is the best engineered and manufactured screw I've ever bought. I used these to tie 2x8s into the perimeter of my patio roof and homes exterior walls as the frame work to screen in my patio. These worked beautifully, I did drill 1/8" pilot holes since I was sinking these near the edges of the boards and wanted to be 100% sure I didn't split the wood. When these screws grabbed a stud in the wall they pulled the 2x8 really tight (like a clamping force) from the little cutting threads on the screw. I will definitely be using this again for all my future projects that require a lag screw.
- TicojonReviewed in the United States on August 7, 2015
5.0 out of 5 stars Highly recommended.
Verified PurchaseThe advantages and ease of a screw with the benefits and strength of a nail. This is the second deck project I used these as structural fasteners; I will look for these for future projects. Highly recommended.
