The Fischer bolt anchor FBN II is a steel anchor designed for economical fixings in uncracked concrete. Thanks to its long thread and two anchoring depths, the Fischer bolt anchor FBN II is particularly versatile. In addition to the pre-insertion and through-insertion installation methods, the bolt anchor is also suitable for spacing installations. The version made of electro-galvanized steel is suitable for railings, cable trays, and brackets in indoor applications.

Advantages: The standard anchoring depth achieves the highest load capacities. This results in fewer fixing points and smaller anchor plates being required. The reduced anchoring depth decreases the drilling depth, which reduces installation effort and increases flexibility. The long thread allows for compensation of component tolerances and spacing installations, thus enhancing flexibility. A few hammer blows and minimal slip during tightening ensure a noticeably easy installation. The impact pin protects the thread from damage and allows for time-saving assembly and disassembly of the attachment.

Applications: Steel constructions, railings, brackets, ladders, cable trays, machines, stairs, gates, facades.

Approved for: Concrete C20/25 to C50/60, uncracked. Also suitable for: Concrete C12/15, natural stone with a dense structure.

Functionality: The FBN II is suitable for pre-insertion and through-insertion installation and is conditionally suitable for spacing installation. Before installation, position the hex nut optimally (the impact pin protrudes about 3 mm from the hex nut). When applying torque, the cone bolt is pulled into the expansion clip and tightens it against the borehole wall. The head marking allows for easy verification of the anchoring. For series installations, we recommend using the bolt anchor setting tool FABS.
