   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.

      NO Split               NO Pre-Drill 

  •  3IN1 multi-function screw prevents the timber splitting, especially near the edge.
