3 in 1

  • Hex-Star Recess- fit well, stable and better driving for load-bearing materials.
  • Twister Thread- Low Driving torque, High holding power, and no split near the edge of timber.
  • Arrowy® - Powerful point for fast drilling.


         It prevents the timber splitting, especially near the edge.


         Comparing with Self-drilling screws with wings, 3 in 1 screw is faster and cheaper for cement board or wood to steel.
