The fischer internally threaded anchor FIS IG is a system component for surface-flush fixings in timber. The metric internal thread in thread sizes M8 to M20 allows the use of standard metric screws or anchor rods. The internally threaded anchor can be removed flush with the surface and the fixing point can be reused. This makes the FIS IG particularly suitable for the assembly of prefabricated components on the construction site. It also allows a particularly safe transport of prefabricated components, as there is no need to use protruding anchor rods with the risk of bending.
