AW drive
- Improved power transmission
- Longer service life
- Optimal centring
- Negligible risk of screw coming loose
Milling head
- Automatic countersinking in all types of wood and wood-based materials
- No cracks in the coating
- No cracks or material splitting with screws at the edges
Shaft
In most cases, no pre-drilling is required thanks to the special thickness of the shaft. This is dependent on the type of wood.
Thread
- Thanks to the asymmetric double-speed thread provided by a plastic sliding layer, the processing time is halved and a 40% higher torque is achieved at the same screw-in resistance when compared to traditional chipboard screws.
Tip
- The 25° tip allows the screw to be easily centred and positioned with precision on hard surfaces.
