GRK Fasteners 01103 9x234 R4 Star Drive Flat Head 480/ProPak

GRK FASTENERS 01103 9x234 R4 Star Drive FH 480/ProPak delivers exceptional performance for both interior and exterior applications. This innovative self-countersinking screw is designed with a patented underhead featuring saw-blade-like cutting teeth and six self-contained cutting pockets. These unique attributes function similarly to a circular saw blade, efficiently removing "drill dust" and ensuring a clean hole even in the most brittle materials, without risking surface treatments. With the ability to countersink into the hardest woods, the R4 screw head seals the hole with precision, preventing any damage to surrounding fibers. Ideal for decking, stairs, and residential construction, this versatile fastener eliminates the need for pre-drilling in most materials, saving you valuable time. The R4 features a Starhead recess that prevents stripping, ensuring a secure fit every time. Designed for use with fibrous materials, the screw comes in a convenient Pro Pak containing 480 screws, making it a great choice for large projects. For optimal performance, use the red driver tip for #6 and #8 screws and the green driver tip for #9 and #10 screws. Experience the reliability and efficiency of GRK Fasteners with the R4 Star Drive screw, your go-to solution for all your fastening needs.
