The Fischer bolt anchor FBN II is a steel anchor designed for economical fastening 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 mounting, the bolt anchor is also suitable for spacing installation. Made of hot-dip galvanized steel, the bolt anchor is ideal for railings, handrails, or brackets.

Advantages: The standard anchoring depth achieves the highest load capacities, resulting in fewer fastening points and smaller anchor plates. 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, further enhancing flexibility. A few hammer blows and minimal tightening slip 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 mounting 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, tightening it against the borehole wall. The head marking allows for easy verification of the anchoring. For serial installations, we recommend using the bolt anchor setting tool FABS.
