The installation-friendly internal thread anchor for fixings in reinforced concrete hollow plates.
The fischer hollow-ceiling anchor FHY is an internal threaded anchor made of A4 stainless steel. The FHY is set into the drill hole by hand via the through-type installation, and then driven in with the hammer until it is surface-flush with the building material. When applying the torque, the cone is pulled into the expansion sleeve. This expands in the cavity and in solid building materials it expands against the drill hole wall. The fischer hollow-ceiling anchor FHY is ideal for fixing timber and steel constructions and consoles in pre-stressed concrete hollow slabs in outdoor areas.
