      Top Features
      • The internal thread design fits perfectly to applications like fixings of pipe routes, channel systems, ventilation ducts and facilities in the building service engineering.

      Your advantages / Product description

      The powerful concrete screw for fast and simple installation.
      Advantages
      • The special thread geometry enables fast cutting into the concrete and allow higher loads.
      • The expansion-free anchorage (undercut) ensures low edge and axial clearances.
      • The ribs under the head prevent accidental loosening of the concrete screw and making the system more secure.
      • The internal thread design fits perfectly to applications like fixings of pipe routes, channel systems, ventilation ducts and facilities in the building service engineering.
      The fischer concrete screw FBS IN I is made of zinc-plated steel with an internally threaded head. The expansion-free anchorage (undercut) ensures low edge and axial clearances. The ICC approval for cracked and non-cracked concrete as well as for seismic loads guarantees even more safety.
