GRK Fasteners 01079 8X212 R4 Star Drive Flat Head Screw 650/ProPak

GRK FASTENERS 01079 8X212 R4 Star Drive FH 650/ProPak is engineered for superior performance in both interior and exterior applications, making it ideal for decking, stairs, and various residential construction projects. This innovative screw features GRK’s patented R4™ design, which includes unique underhead cutting teeth and six self-contained cutting pockets. These elements work together to create a clean, precise hole in even the most brittle materials, minimizing the risk of surface treatment cracking. Notably, the R4™ self-countersinking capability allows the screw to sink flawlessly into hard woods without damaging surrounding fibers, ensuring a professional finish every time. With extreme threads for enhanced grip, these screws eliminate the need for pre-drilling, simplifying your installation process. The starhead recess helps prevent stripping, providing reliable performance across a variety of fibrous materials. This Pro Pack contains 650 screws, each measuring #8 x 2-1/2", making it an excellent choice for large projects or frequent use. For optimal results, use the red driver tip for #6 and #8 screws, and the green driver tip for #9 and #10 screws. With GRK FASTENERS, you can trust in quality craftsmanship and innovative design for all your fastening needs.
