R4 SS Bulk by GRK
Self-tapping, countersinking head, W-Cut thread design, CEE Thread, Zip-Tip™, and Climatek™ coated. For use in wood, particle-board, cement fiberboard, plastic, sheet metal, etc.

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 screw head closes the hole off with precision, leaving no damaged fibers around the head.
