Grk Fasteners 01105 R4 #9 X 3-1/8 In. Star Drive Framing Screws, 425 Pk

GRK Fasteners R4 screws are self-countersinking wood screws engineered for framing, decking, and general construction applications. The patented underhead design features saw-blade-like cutting teeth and six self-contained cutting pockets that work together to transport drill dust away from the hole edge, creating clean, precise holes even in brittle materials without surface cracking. This advanced design allows the fastener to countersink smoothly into even the hardest woods, with the screw head closing the hole with precision and leaving no damaged fibers.

The Climatek coating provides excellent corrosion resistance, making these screws suitable for use in treated lumber and outdoor applications where longevity is essential. With 425 screws per pack, you have ample supply for large framing projects, multiple jobs, or professional use. The #9 thread size and 3-1/8 inch length make these screws versatile for a wide range of wood fastening tasks, whether working indoors or outdoors.

Features and Benefits
