GRK Fasteners RSS™ 5/16 x 3-1/8 Inch, Structural Screws, 100 PCS, Rust Resistant Climatek™ Coating, Heavy-Duty Framing & Decking Screws, Fast Bite Tip, Star Drive Recess, T-30 Bit Included, Gold

Product Description The GRK RSS Rugged Structural Wood Screw is a professional-grade fastener designed for heavy-duty framing, decking, and construction projects. These premium screws deliver superior performance in applications, including deck building, timber framing, laminated beams, pole barns. GRK’s Climatek coating, provides exceptional corrosion resistance, making these construction screws ideal for pressure-treated lumber, cedar, and all other wood applications. The patented Fast Bite Tip and Zip-Tip technology eliminates the need for pilot holes, while the W-Cut design ensures smooth, low-torque driving in all wood types. ICC-ES ESR-2442 approved for structural applications, these self-drilling screws are trusted by professional builders and DIYers alike. The star drive head with 6-points of contact prevents cam outs and head stripping, making these wood screws the choice for demanding construction and home improvement projects. 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.

• Heavy Duty Lag Screw Alternative: Eliminates pre-drilling in most woods with Zip-Tip technology. Installs 3x faster than traditional lag screws
• ESR-2442 Code Approved For Structural Applications: Engineered for professional-grade connections in heavy duty framing, multi-ply beams, and timber framing. Integrated washer head delivers maximum clamping force for zero-gap joints in LVL, LSL, and engineered lumber.
• Advanced Corrosion Protection: Rust resistant Climatek coating provides exceptional durability for outdoor use and in pressure-treated lumber applications
• W-cut Thread Design: Reduces installation torque by 40% for smoother, faster driving. CEE threads minimize splitting in dense hardwoods, engineered lumber, and laminated beams.
• Precision Engineering: Star/Torx drive recess with 6 points of contact prevents stripping and minimizes wobble between screws and bits.
