High performance anchor FH II-I

Strong, secure and aesthetic with internal thread for the removal option of the attachment

The fischer high-performance anchor FH II-I is an internal threaded anchor made from zinc-plated and stainless steel. The FH II-I is ideally suited for anchoring air conditioning units, machines, and stadium seating in cracked and non-cracked concrete. The European Technical Approval and classification as per fire resistance class R 120 guarantee added safety. Furthermore, the international approvals cover applications in earth quake regions (Seismic C1 and C2). During the installation with a hexagonal key, the cone is pulled into the expansion sleeve and expands it against the drill hole wall. The FH II-I enables the best possible adjustment in line with the fixture with metric screws and threaded rods. The internal threaded anchor also allows surface-flush removal and the reuse of the fixing point.

Product Description

Advantages

The international approvals guarantee maximum safety and the best performance.
The internal threaded anchor allows the removal of the attachment and the fixing point can be reused.
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.

Assembly Instruction

Functioning

The FH II-I is suitable for pre-positioned installation.
When a hexagon wrench is used for installation, the internal thread bolt starts to rotate. This pulls the cone into the expansion sleeve and expands it against the drill-hole wall. At the same time, the anchor is tightened through compression of the black plastic ring. A gap U to the concrete surface is created (see image 4).
The anchor is set according to the approval when the gap U is 3-5 mm. Alternatively, an installation torque of T_inst can also be applied.
