#12/14 x 10" R4 Multi-Purpose Framing Screw (50/Pack)
GRK’s R4™ self-countersinking screw has a patented underhead with sawblade like cutting teeth and six self-contained cutting pockets. Together they act similar to a circular sawblade, transporting the drill dust away from the edge of the screw hole while cutting a perfectly clean hole into even the most brittle materials without cracking any surface treatment.
- Zero stripping with 6 points of contact.
- Enlarges hole to reduce splitting.
- Low torque, smoother drive, reduced splitting.
- No pre-drilling, faster penetration.
