A2 stainless steel, full thread, countersunk milling head, AW recess
AW recess
- Better power transmission
- Longer service life
- Optimal centring
- Low risk of screws coming loose
Milling head
- Automatic countersink milling in all types of wood and engineered wood
- No cracks in the coating
- No cracks or material splitting with screws on the edges
Shank
In most cases, no pre-drilling is required due to the special thickness of the shank. This depends on the type of wood.
Thread
- The asymmetrical double-start thread with plastic glide layer halves the working time and achieves a torque that is 40 % higher than conventional chipboard screws with the same screw resistance.
Tip
- The 25° tip allows for easy centring and precise positioning of the screw on hard surfaces.
NoticePatented according to 0504782
