TX drive
- Six force application areas (line contact) for strong power transmission
- No driving-out effect (cylindrical shape eliminates cam-out effect) for a long bit service life
- Mechanical processing possible
- Good torque transmission
Hexagon drive
- Six force application areas for optimal power transmission
- Can be mechanically driven
- Very good torque transmission
Pressed-on washer
- High tightening and head penetration values
- High degree of tension resistance
- Shorter installation times, as no additional washer is required
Under-head reinforcement
- Optimal tear-off resistance enhances user safety
Partial thread
- Optimal finish due to tight sealing of the top layer of wood
End mill (friction part)
- Less friction on the screw shaft minimises tool damage
- Less power and force required as it functions like a drill bit
- Lower screw-in resistance
- Easy to install long screws
Coarse thread
- Always provides the optimum speed for each screw length
- The thread geometry enables faster screwing in, saving time during processing
High-quality hardened steel
- High breaking torque
- Optimal installation quality
Anti-friction coating
- Easy to screw in with low screwing resistance, reducing the amount of energy and force required
Cutting point
- Low splitting forces due to drilling effect
- Reduced splitting tendency of the wood enables edge connection
- Chipping of the wood fibres
The wood construction screw with pressed washer is used primarily for wood/wood connections in structural timber construction (e.g. for on-roof rafter insulation, wooden frame construction, roof truss construction, element construction, prefabricated building, staircase construction, etc.).
Installation must be carried out in accordance with the European technical assessment (ETA)!
