The cost-efficient fixing for flexible use in non-cracked concrete.

Bolt anchor FBN II

The fischer bolt anchor FBN II is a steel anchor for cost-effective fixations in non-cracked concrete. Thanks to its long thread and the two anchorage depths, the fischer bolt anchor FBN II is particularly flexible. In addition to pre-positioned and push-through installation, the bolt anchor is suitable for stand-off installation. In the stainless steel design, the bolt anchor is suitable for façade sub-structures, cantilevers, and ladders outside.

Advantages

The standard anchorage depth achieves the maximum load-bearing capacities. Thus 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 long thread balances component tolerances and allows for stand-off installations, thus increasing flexibility.
Few hammer blows and the minimal torque slippage allow for a noticeably simpler installation.
The drive-in pin protects the thread from damage, and thus ensures a faster installation and dismantling of the attachment.

Functioning

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.
