GRK PHEinox™ Stainless Steel R4 Multi-Purpose Screws

  • GRK's R4™  multi-purpose self-countersinking screw has six self-contained cutting pockets which act like a router and transport the "drill dust" away from the edge of the screw hole.
  • Made from PHEinox ™ hardened stainless steel with a Star Drive
  • Widens the countersink hole only around the head shape. The head top closes the hole exactly, leaving no damaged fibers around the wider area of the head.
  • Pre-countersinking is no longer required, it is done by the screw itself
