Description: - Unique 24 slots cut into the underside of the head - self countersinks into all material without the need to counter bore and without surface damage.
- Double reinforced collar - significantly strengthens the underside of the head, preventing snapping and allowing a deeper pozi recess.
- Sharp, wide, deep thread formation coated with a unique lubricant.
- Sharp saw tooth formation cut out of the bottom threads - on insertion the threads bite into the timber reducing torque and resistance, enabling fast penetration without a pilot hole.
- Specifically positioned long thin groove - dramatically reduces pressure build up on insertion by dispensing wood fibres, preventing splitting when screwing close to the edge.
- Razor sharp point as low as 20 degrees, with a thread that extends to the tip of the screw - giving you an immediate start even with the hardest, smoothest surfaces.
