  • SawTooth® point guarantees quick starts, lowers installation torque, and eliminates the necessity for predrilling in most scenarios
  • Underhead nibs enable the head to countersink into wood with minimal splintering
  • Large washer head offers maximum bearing area (0.650" washer head diameter)
  • Size identification featured on all SDWH screw heads
  • 5⁄16" hex drive for easy installation
