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 stainless steel screws, provide superior corrosion resistance, making these construction screws ideal for applications exposed to corrosive environments. Use 305 stainless steel screws for applications such as pool decking, docks, boardwalks, and lake piers. Use 316 stainless screws for environments with high exposure to chlorides, such as de-icing salts, and applications near the coast. 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 outs and head stripping, making these wood screws the choice for demanding construction and home improvement projects.
