fischer bolt anchor FBN II 20/30 hot-dip galvanised

Top Features

With assessment document (ETA) the hot dipped galvanised steel version is covered for external use with variable working life depending on environment and corrosion conditions.
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.
Simple assembly due to few taps and minimal slippage.

The cost-efficient fixing made of hot-dip galvanised steel for use in non-cracked concrete.

Advantages

The standard anchorage depth achieves the maximum load-bearing capacities. This means that fewer fixing points and smaller anchor plates are required.
The reduced anchorage depth reduces the drill hole depth. This minimises the amount of time needed for installation whilst increasing flexibility.
The first bolt anchor with variable working life covers the usage of bolt anchors in wet conditions and outdoor areas.
The long thread balances component tolerances and stand-off installations, and thus increases flexibility.
Fewer hammer blows and the minimal torque slippage allow for a noticeably simpler assembly.
The drive-in pin protects the threaded screw from damage, and as such ensures a faster installation and dismantling of the fixture.

The fischer bolt anchor FBN II is a steel anchor for cost-effective fixings in non-cracked concrete. Due to the long thread and the two anchorage depths, the fischer bolt anchor FBN II can be used in a particularly flexible manner. The bolt anchor is also suitable for stand-off installation as well as pre-positioned and in push-through installation. The stainless steel version of the bolt anchor is suitable for fixing façade sub-structures, consoles, and ladders in external areas.

Functionality

The FBN II is suitable for pre-positioned and push-through installation; also suitable for stand-off installation under certain conditions.
Prior to installation, place the hexagon nut in the optimal position (the drive-in pin projects by approx. 3 mm out of the hexagon nut).
When applying the torque, the cone bolt is pulled into the expansion clip and expands it against the drill hole wall.
The head embossing offers a simple control of the anchoring.
In the case of series installation, we recommend using the FABS bolt anchor setting tool.
