GRK Fasteners-00137 772691001375 R4 Bulk Number-10 by 3-1/8-Inch Screw, 1500-Count, #10 x 3-1/8", Gold, 1500 Count

Product Description GRK Fasteners-00137 772691001375 R4 Bulk Number-10 by 3-1/8-Inch Screw, 1500-Count, #10 x 3-1/8", Gold, 1500 Count From the Manufacturer GRK's R4 self countersinking screw has a new 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 also further enhances the R4's versatility by allowing the fastener to be installed without countersinking into even the hardest woods. The screw head closes the hole off with precision, leaving no damaged fibers around the head.
