SCREW R4 STAR PPK 9X2-3/4IN SCREW R4 STAR PPK NO10X4.314IN SCREW M/P FRAME/DECK 10X4IN
#6 and #8 screws use T-15 bit; #9, #10, and #12 use bit T-25. Self-tapping, countersinking head; W-Cut thread design. Climatek coated for all weather corrosion protection conforms with ICC#2442. For use in wood, particle-board, cement fiberboard, plastic, and sheet metal. 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 perfectly clean hole into even the most brittle materials without cracking any surface treatment. This design enhances the R4's versatility by allowing the fastener to countersink into even the hardest woods. The head of the screw closes the hole off with precision leaving no damaged fibers around the head. R4??? screws 2 in and longer have a four threaded CEE thread. This enlarges the screw hole for the non-threaded portion of the fastener, allowing the wood to settle easily. It increases the screw's drawing strength and reduces the friction on the screw shank that lowers the driving torque.
