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.
