Fischer Bolt Anchor FBN II 20/120 (20X277) Hex Bolts - Zinc Plated

Product Description

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

Features

• 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 drive-in pin protects the thread from damage. This saves time during installation and removal.

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.

Applications

• Steel constructions
• Guard rails
• Consoles
• Ladders
• Machines
• Gates
• Façades

Building Materials

Approved for:

• Concrete C20/25 to C50/60, non-cracked

Also suitable for:

• Concrete C12/15
• Natural stone with dense structure

Permission

• ETA-07/0211
• DoP 0192
• DoP No. 0015

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.
