3IN1 Multi-Function Screw
Carbon steel、302、304、305、316 Stainless Steel
Hex-Star Recess Size
1. Wood to Wood
2. Cement Board (Hardi-board or Wood) to Steel
3. Steel to Wood (Plywood, OSB or Wood Purlins)
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.
- 3IN1 multi-function screw prevents the timber splitting, especially near the edge.

Right: 3IN1 multi-function screw v.s. regular screw drilled 12mm from the edge of yellow pine.
- Comparing with self-drilling screws with wings tek, 3IN1 multi-function screw is faster and cheaper for cement board or wood to steel with the flat finished surface.
