Internal threaded sockets FIS E

The internal threaded anchor for masonry and aerated concrete

The fischer internal threaded anchor FIS E is a system component for use with the fischer injection mortars FIS V, FIS VL, FIS P Plus, FIS P, and FIS Green for fixations in masonry made from solid brick, perforated brick, and aerated concrete. When the threaded anchor is installed, the mortar is pressed through the grating structure and creates a form fit with the structure of the brick. The metric internal thread enables the use of conventional metric screws or threaded rods. The internal threaded anchor is suitable for surface-flush removal, and the fixing point can be reused. This means that the FIS E is particularly suited to detachable and temporary fixings both inside and outside. The approvals of the various injection mortars must be observed.

Product Description


  • The internal threaded anchor FIS E is suitable for use with injection mortar in masonry or aerated concrete.

  • The internal threaded anchor FIS E allows for surface-flush removal and the reuse of the fixing point, and therefore offers the best possible flexibility.

  • The metric internal thread allows for the use of standard metric screws or threaded rods, which enables ideal adaptation in line with the intended use.

  • Please refer to the approvals for the mortar used.
