Description

The GRK Fasteners R4 No. 10 x 3-1/8 in. star drive countersink screw is a self-countersinking fastener designed for framing, decking, and general construction projects in both indoor and outdoor environments. Its patented underhead features saw-blade-like cutting teeth and six self-contained cutting pockets that work together to transport drill dust away from the screw hole edge while cutting cleanly into even brittle materials without cracking surface treatments.

These screws eliminate the need for pre-drilling and countersinking, saving time on every installation. The countersink head closes the hole with precision, leaving no damaged fibers or rough edges around the fastener head. The Climatek corrosion-resistant coating ensures long-term durability in treated lumber and harsh outdoor conditions, making this a reliable choice for both professional builders and DIY enthusiasts tackling home renovations or commercial construction projects.

Features and Benefits

  • Patented Self-Countersinking Design: The underhead with cutting teeth and pockets transports drill dust away while cutting a perfectly clean hole into hard woods without requiring pilot holes or separate countersinking.
  • Climatek Corrosion-Resistant Coating: Protects against rust and degradation in treated lumber and outdoor environments, extending the life of your fasteners in any condition.
  • Star Drive Head: The star drive minimizes cam-out and stripping, providing secure engagement and improving installation efficiency.
  • Four-Threaded CEE Thread: On 2-inch and longer screws, the four-threaded CEE thread enlarges the pilot hole for the non-threaded shank, allowing wood to settle easily, increasing drawing strength, and reducing driving torque.
  • Fast Bite Tip: Enables rapid penetration and eliminates the need for pre-drilling, accelerating project completion.
  • Versatile Multi-Purpose Application: Ideal for framing, decking, railings, and remodeling tasks, suitable for both indoor renovations and professional construction work.
