Fischer 507577 Bolt Anchor FBN II 8/50 Hot-Dip Galvanised (Pack x 50)

• 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

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

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.
