GRK's R4™ self-countersinking screw has a patented underhead with saw blade like cutting teeth and six self-contained cutting pockets. Together they act similar to a circular saw-blade, transporting the drill dust away from the edge of the screw hole while cutting a ideally clean hole into even the most brittle materials without cracking any surface treatment.
- Fast bite tip eliminates pre-drilling and provides a fast start for one-step installation
- W-Cut™ low installation torque allows for fast driving and ease of install
- Precision fit reduces wobble between R4 screws and GRK bits for improved productivity
- Star drive, zero stripping, with six points of contact
- Improves clamping force for increased drawing power
- CEE Thread™ enlarges hole to reduce splitting
- Cutting teeth cuts wood fiber and provides flush seating
- GRK head markings easy identification of genuine GRK screws
