The large washer increases the size of the supporting surface. For the fixing of timber constructions.
Pre-assembled washer saves time during installation.
The FBN II achieves maximum load-bearing capacity with standard anchorage depth. This means: fewer fixing points and smaller anchor plates.
If the reduced anchorage depth is used, then this lowers the drill hole depth and simplifies installation.
Component tolerances are balanced out with the long thread. In addition, FBN II is also suitable for stand-off installations. This increases flexibility.
