R4 01101 #9 X 2-1/2 In Star Drive Framing Screws, Steel, 575 Pk

GRK Fasteners R4 screws are self-countersinking fasteners engineered for professional-grade framing, decking, and general wood construction. The patented underhead design features saw-blade-like cutting teeth and self-contained cutting pockets that work together to transport drill dust away from the screw hole while cutting a clean, precise opening into even brittle materials without cracking or splintering the surface. This innovative construction allows the fastener to countersink smoothly into the hardest woods and treated lumber, closing the hole with precision and leaving no damaged fibers around the head.

These steel screws are coated with Climatek protection, offering reliable corrosion resistance in both indoor and outdoor applications, making them suitable for harsh weather conditions and treated lumber exposure. The #9 x 2-1/2 inch length with four-threaded CEE thread design reduces driving torque while increasing drawing strength, enabling faster installation and reducing labor time without the need for pre-drilling. With 575 screws per pack, you'll have a dependable supply for substantial framing projects.
