Features and benefits

1. Cylindrical head with TX socket

Allows for quick and invisible countersinking of the screw into the fastened element. The TX socket guarantees optimal torque transfer.

2. Thread under the head

Ensures optimal counterbatten fastening and allows the load to be transferred from the counterbatten through the screw to the rafters, bypassing the insulation. Protects the insulation from damage.

3. Countersinking cutter

Reduces the torque required for screwing by widening the hole in the fastened element.

4. Wax Coating

Thanks to the special wax coating applied during the manufacturing process, the screwdriving torque has been significantly reduced.

5. Double Thread

Additional coils on the tip facilitate screwdriving - they allow for faster "gripping" of wood with less pressure.

6. Milling Tip/Cutting Notches

Special milling tip shape, up to 20% less resistance during screwdriving, which extends the life of the battery and the tools themselves. Cutting notches on the thread cut the fibers of the wood structure during screwdriving.

7. High Torque

Enables screwdriving without pre-drilling in hard types of wood.

1. Wood solid,

2. Glued solid wood (CLT,KVH,BSH/GLT)

3. Laminated laminated timber (LVL)

1. Installation of soft over-rafter insulation (insulating materials with low compressive strength (σ(10%) < 50 kPa - EN 826))

2. Installation of insulation on the facade

3. Installation of hard over-rafter insulationInsulating material with high compressive strength (σ(10%) ≥ 50 kPa - EN 826)

4. Wooden structures.
