#10 x 3-1/2" R4 Multi-Purpose Framing Screw (50/Pack)

#10 x 3-1/2" 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.
