GRK Fasteners 01099 9x2 R4 Star Drive FH 690 ProPak

GRK FASTENERS 01099 9x2 R4 Star Drive FH 690/ProPak delivers exceptional performance for both interior and exterior projects. This self-countersinking screw features a unique patented underhead design equipped with saw-blade-like cutting teeth and six self-contained cutting pockets. These innovative characteristics work together to create a perfectly clean hole in even the most brittle materials, minimizing the risk of surface cracking. Designed for versatility, the R4™ screw effortlessly countersinks into hard woods while ensuring that the screw head closes off the hole with precision, leaving no damaged fibers around it. This makes it an ideal choice for decking, stairs, and various residential construction applications. The screw can be used without pre-drilling in most cases, streamlining your workflow. With a size of #9 x 2" and featuring a Starhead recess to prevent stripping, these screws are compatible with fibrous materials. For optimal performance, use the red driver tip for #6 and #8 screws and the green driver tip for #9 and #10 screws. Each Pro Pak contains 690 screws, making it a practical option for larger projects. Discover the efficiency and reliability of GRK FASTENERS for your next building endeavor.
