Frame fixing FUR with countersunk head

The fischer frame fixing FUR consists of a plug sleeve made from high-quality nylon and a countersunk head screw made from zinc-plated steel or stainless steel. When the screw is screwed in, the asymmetrically arranged lamella teeth expand evenly against the wall of the drill hole in the solid building material. In hollow materials, the teeth expand through the solid part of the block and form an undercut in the cavity. The functional principle enables an even load application without extreme expansion pressure and simplifies installation even in the case of an unknown mounting substrate. The FUR is offered in diameters of 8 mm and 10 mm up to a fixing length of 230 mm. The European Technical Approval for the FUR 10 offers added safety. The FUR with countersunk head screw is particularly suitable for the fixing of substructures made of wood.
