Description

Self-clearing groove in the tip area

The self-clearing groove milled into the tip inhibits splitting forces exerted by the screw in wood, in particular where the screw is used close to edges.

Special countersunk head, D = 7.2 mm, with light lens and under-head restraining grooves

• Special head shape — head fits cleanly in the fitting.
• Under-head restraining grooves to prevent over-tightening of the screw in the fitting.

Machine capable AW drive system

• Better force transfer
• Longer service life of the bit
• Optimum centring
• Largest possible contact surface

Asymmetrical thread

Single-start thread with sharp tip. Screw with ring thread and self-clearing groove in tip area, preventing splitting of wood even when working close to edges. The screw-in torque is considerably lower than with standard chipboard screws, which extends the service life of the processing machine and the bit insert.
