High performance anchor FH II-SK

Strong, secure and aesthetic for a flush-mounted fixing

The fischer high-performance anchor FH II-SK with its countersunk head is a sleeve anchor made from zinc-plated and stainless steel for visually demanding anchorings. The FH II-SK is ideal for anchoring railings, steel constructions, and staircases 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) The anchor is set into the fixture flush with the surface in a time-saving push-through installation. When the screw is tightened, the cone is pulled into the expansion sleeve and expands it against the drill hole wall. This pulls the fixture onto the base material. The black plastic ring prevents the undesired turning of the anchor and takes the torque slippage.

Product Description

  • 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 countersunk finished screw head allows for flush-mounted fixing.
  • 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 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).
