GRK Fasteners 01101 9x212 R4 Star Drive Flat Head Screw 575/ProPak

GRK FASTENERS 01101 9x212 R4 Star Drive FH 575/ProPak offers an innovative solution for both interior and exterior construction projects. This pack includes 575 screws, each designed with a patented underhead featuring saw-blade-like cutting teeth and six self-contained cutting pockets. This unique design functions like a circular saw blade, effectively transporting drill dust away from the screw hole, resulting in a clean and precise cut even in brittle materials. The R4™ self-countersinking screw is ideal for decking, stairs, and residential construction, eliminating the need for pre-drilling in most cases. Its starhead recess prevents stripping, while the extreme threads ensure a strong grip, making it suitable for fibrous materials as well. The screw head is engineered to close off holes perfectly, preventing damage to surrounding fibers. For optimal usage, a red driver tip is recommended for #6 and #8 screws, while the green driver tip is designed for #9 and #10 screws. With a length of 2-1/2 inches and a weight of 5.18 pounds, this versatile fastener adapts seamlessly to various applications. Trust GRK Fasteners to deliver quality and precision for your next project.
