GRK Fasteners 96085 UberGrade Star Flat Head Multi-Purpose Screw

  • Cutting teeth cuts wood fiber and provides flush seating
  • Zip-Tip eliminates pre-drilling for one step installation
  • Star drive eliminates stripping for improved productivity
  • W-cut low installation torque allows for fast driving and ease of install
  • Ground contact lumber approved for worry free use in pressure treated lumber

GRK’s R4 Self Countersinking screw has 6 self-contained cutting pockets which act like a router and transport the drill dust away from the edge of the screw hole. They also widen the countersink hole only around the head shape. The screw head top closes the hole exactly, leaving no damaged fibers around the wider area of the head. The R4 head design is so effective that it will not crack even the most brittle materials.
