GRK Fasteners R4™ #9 x 3-1/8 Inch, Multi-Purpose Framing Screws, 1900 PCS, Rust Resistant Climatek™ Coating, Outdoor Fencing and Deck Screws, Fast Bite Tip, Star Drive Recess, Gold

Product Description The GRK R4 Multi-Purpose Wood Screw is a professional-grade structural fastener designed for framing, decking, and construction projects. These premium screws deliver superior performance in both interior and exterior applications, including deck building, fencing, and general carpentry. 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-3201 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 out and head stripping, making these wood screws the choice for demanding construction and home improvement projects. From the Manufacturer GRK's R4 self countersinking screw has a new underhead with saw-blade like cutting teeth and six self-contained cutting pockets. Together they act similar to a circular saw-blade, transporting the drill dust away from the edge of the screw hole while cutting a perfectly clean hole into even the most brittle materials without cracking any surface treatment. This design also further enhances the R4's versatility by allowing the fastener to be installed without countersinking into even the hardest woods. The screw head closes the hole off with precision, leaving no damaged fibers around the head.
