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 pre-insertion and through-insertion installation, the bolt anchor is also suitable for spacing installation. The version made of galvanized steel is suitable for railings, cable trays, and brackets in indoor applications.

Advantages: The standard anchoring depth achieves maximum load capacities, which means fewer fixing points and smaller anchor plates are required. The reduced anchoring depth decreases the drilling depth, thereby reducing installation effort and increasing flexibility. The long thread allows for compensation of component tolerances and spacing installations, further enhancing flexibility. A few hammer strikes and minimal tightening slippage ensure 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 conditionally for spacing installation. Before installation, position the hex nut optimally (the impact pin protrudes about 3 mm from the hex nut). When applying the torque, the cone bolt is pulled into the expansion clip and tensions it against the borehole wall. The head marking allows for easy verification of the anchoring. For series installation, we recommend using the bolt anchor setting tool FABS.
