High-load fastening with Fischer FH II 10/25 H

Practical benefits

High shear load capacity: The optimized design between the bolt and sleeve delivers impressive load values, ensuring you require fewer fixing points in concrete.
Secure and controlled expansion: Tightening pulls the cone firmly into the sleeve against the borehole wall, while the plastic ring prevents unwanted anchor rotation.
Fast and effortless installation: With its push-through installation design and optimized geometry, you secure heavy fixtures quickly and with noticeably reduced setting energy.

In a nutshell

The right choise for

With the Fischer fh II 10/25 h high-performance anchor, you achieve reliable heavy-duty fastenings in cracked and non-cracked concrete. The optimized interaction between the steel sleeve and the bolt delivers high load and shear capacities, allowing you to use fewer fixing points. The push-through installation saves valuable time, letting you drill a 10 mm hole directly through fixtures up to 25 mm thick into the base material. As you tighten, the expansion cone secures firmly against the borehole wall while the plastic ring prevents unwanted rotation. The zinc-plated cap nut provides a clean, safe, and visually appealing finish without sharp protruding threads on railings, brackets, or steel structures.

Product description

The through bolt anchor with cover nut and sophisticated design in cracked concrete.

The fischer high-performance anchor FH II H with cover nut is a sleeve anchor made of zinc-plated steel. The anchor is set in the time-saving through-type installation. When tightening the anchor, the cone is pulled into the expansion sleeve and expands it against the hole wall. The black plastic ring prevents the anchor from rotating and absorbs the torque slippage. This means that the fixture is pulled towards the anchoring base. The fischer high-performance anchor FH II H with cover nut is ideally suited to fix steel constructions, machines, and gates in cracked and non-cracked concrete.

With cover nut
The international approvals guarantee maximum safety and maximum performance. Also for applications in earthquake regions (seismic C1 and C2)
The ideal combination of screw shank and sleeve enables a high transverse load capacity and fewer fixing points
The optimised geometry intelligently reduces the setting energy and thus ensures a force-saving assembly
The international approvals guarantee maximum safety and the best performance. The European Technical Assessment even cover use in earthquake zones (seismic C1 and C2)
The protruding head for stable and robust fixings
The design between the bolt and the sleeve ensures high shear load-bearing capacity. Thus, fewer fixing points are required
The optimised geometry intelligently reduces the energy required for assembly
The approval regulates the use of hollow drills

Suitable for

The FH II is suitable for push-through installation
When applying the torque, the cone is pulled into the expansion sleeve and expands it against the drill hole wall
The black plastic ring prevents rotation when tightening the anchor, and acts as a crumple zone to take the torque slippage so that the fixture is pulled onto the anchor base
Available head shapes for flexible design solutions:Countersunk head (type SK), hexagon head (type S), bolt version with nut and washer (type B) and cap nut (type H)
