Hollow ceiling anchor FHY drill diameter 12mm M8 R stainless steel FISCHER

The fischer FHY hollow-core slab anchor is an internally threaded anchor made of A4 stainless steel. The FHY is push-through installed manually into the drill hole and driven flush with the surface of the building material using a hammer. When torque is applied, the cone is pulled into the expansion sleeve. In the hollow space, it expands, and in solid building material, it braces against the drill hole wall. The fischer FHY hollow-core slab anchor is ideal for fastening timber and steel constructions and brackets in prestressed hollow-core concrete slabs in outdoor areas. Marketing Claim: The easy-to-install internally threaded anchor made of A4 stainless steel for fastenings in prestressed hollow-core concrete slabs. Advantages: Due to the anchor's operating principle, the FHY can be used in hollow spaces or solid building materials up to 5 cm from the prestressing steel. This ensures maximum flexibility and ease of installation. The embossed rim prevents the anchor sleeve from slipping too far into the hollow space, enabling problem-free installation. The optimized geometry minimizes the setting energy, allowing use in very confined spaces. This ensures user-friendly installation. The metric internal thread allows the use of standard screws or threaded rods for ideal adaptation to the application. Top Features: Maximum flexibility and ease of installation: Anchor expands in hollow spaces and solid building materials and can be placed up to 5 cm from the prestressing steel. Comprehensive range for fastenings in indoor and outdoor areas. General building inspectorate approval for single fastenings and ETA approval for multiple fastenings as an additional safety bonus. Fire protection approval applies from a mirror thickness of 25 mm for even more versatile applications. Fast and easy installation without special tools.
