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

The fischer bolt anchor FBN II with large washer 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 steel anchor, made of zinc-plated steel and with a large pre-mounted washer, is recommended for fixing bearing beams and sills, as well as other timber constructions.

Top Features:

• 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.

Functioning:

• The FBN II GS 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.

Advantages:

• The larger washer included with the FBN II GS creates a large supporting surface and, as such, allows for use in wood construction.
• The pre-fitted washer ensures a fast assembly.
• The standard anchorage depth achieves the maximum load-bearing capacities. This means that fewer fixing points and smaller anchor plates are required.
• The anchor is also ideal for large fixture thicknesses.
• 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.

Applications:

• Anchor plates with slotted holes
• Façade sub-structures with slotted holes
• Timber constructions
• Tension anchor
• Anchoring of wooden beams
