GRK FASTENERS 01095 9x112 R4 Star Drive FH 820/ProPak offers a reliable solution for your fastening needs, whether for interior or exterior applications. This Pro Pack contains 820 screws, each designed with GRK’s innovative R4™ self-countersinking technology. The unique underhead features patented saw-blade-like cutting teeth and six self-contained cutting pockets, which work together to create a clean hole in even the most brittle materials without causing surface cracks. The R4™ screw excels in versatility, easily countersinking into tough woods while ensuring a precise finish that minimizes fiber damage around the head. With extreme threads and a starhead recess, these screws prevent stripping, making them ideal for decking, stairs, and various residential construction projects. No pre-drilling is necessary unless the material specifically requires it, allowing for a quicker and more efficient installation process. To enhance usability, the red driver tip is recommended for #6 and #8 screws, while the green driver tip is suited for #9 and #10 screws. With a length of 1-1/2 inches, these screws are perfect for a wide range of projects, ensuring secure and durable results every time.
