fit well, stable and better driving for load-bearing materials.
Low driving torque, high holding power and no split near the edge of timber.
Powerful point for fast drilling.
3IN1 multi-function screw prevents the timber splitting, especially near the edge.
Left: 3IN1 multi-function screw v.s. regular screw drilled 9mm from the edge of treated wood.
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.
