Joins wood without causing cracks
Special tapered flat head Ø 7.2 mm slightly raised and with ribs under the head to avoid surface damage.
- Thanks to the special shape of the head, it fits the shape of the connector
- With the braking ribs under the head, the screws can be prevented from turning in the connector
AW machine drive system
- Improved power transmission
- Longer service life
- Optimal centring
- Largest possible contact surface
Asymmetrical entry thread with sharp tip.
- Fast drilling and precise positioning
- Low screwing torque extends the life of the machining machine and the insert
- High torque required to turn the thread in the material
- Faster screwing than with ordinary chipboard screws
Ring-shaped thread — reduced tendency to crack wood when screwing in
- Minimal separation forces, especially when twisting at the edges.
- Reduction in bolt torque
- The risk of cracking is eliminated by the use of an annular thread
For indoor use only! In such cases, ASSY stainless steel screws should be used.
In order to fix metals to wood, a precise cut-out must be made in the metal plate using a flat awl.
ETA-11/0190
ETA-11/0190 approval must be observed when using these screws.

The special head with locating grooves makes it ideal for the entire wooden window frame and furniture making.
In the case of softwood or softwood materials, installation can be carried out without pre-drilling. In order to reduce the distance between the edges, a hole must be drilled according to the diameter for the thread. When screwing into hardwood, drill in accordance with ETA-11/0190 approval.
