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

  • 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

  • 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 Tinst can also be applied.
