Fischer Cavity Dowel 45 mm 8 mm 519770 50 pcs.519770)
The Fischer HM 4x45 S cavity metal anchor is a high-quality fastening solution engineered for secure and durable fixings in hollow building materials. Designed specifically for use in cavity walls and panel materials such as plasterboard and chipboard, this anchor provides reliable load transfer through its metal expansion arms that spread out behind the board. The delivered pack contains 50 pieces, making it ideal for both professional users and demanding DIY projects.
With a shaft diameter class of 4 mm and a length of approximately 45 mm, the HM 4x45 S is suitable for standard wall thicknesses in interior construction. The metal construction ensures high stability, resistance to aging and temperature, and a secure hold even under long-term loads. Typically, this anchor is used in combination with a metric screw of matching size (not included, depending on configuration), which allows flexible adaptation to the attached component.
Typical applications include the mounting of lights, small wall cabinets, shelves, rails, curtain rods, pictures, hooks and various household accessories on cavity walls. The anchor is inserted in the pre-drilled hole and, when the screw is tightened, the metal segments fold out behind the panel, forming a large supporting surface. This distributes the load and significantly reduces the risk of tearing out compared to simple plastic plugs or direct screws in plasterboard.
Advantages of the Fischer HM 4x45 S include the all-metal design for high load capacity, reliable function in many common panel materials, and easy installation with standard tools. The spread-out metal segments provide a secure, vibration-resistant fastening, which is particularly advantageous for frequently used or slightly loaded fixtures. The predefined dimensions help ensure consistent assembly quality and planning reliability for tradespeople and installers.
