Screw/bolt pack FISCHER 564792 — 50 pieces

The fischer DuoPower is an intelligent two-component universal wall plug that combines three anchoring functions in a single product. It adapts automatically to different base materials by folding, expanding and knotting to transfer loads reliably. Mechanical feedback when driving the screw provides a clear indication that the plug is correctly engaged. Certain dimensions of DuoPower have a European Technical Assessment (ETA) for load-bearing applications in concrete and masonry.

Advantages

The DuoPower plug works in a wide range of building materials, reducing the need to stock multiple plug types. Its three-function design—folding, expanding and knotting—ensures secure fixation in both solid and hollow substrates. The plug gives tactile feedback during screw insertion, improving installation confidence. Selected sizes with ETA provide verified performance for safety-relevant fixings in concrete and masonry.

Suitable for

• Fixing shelves, cabinets and furniture to solid walls
• Anchoring in hollow block, aerated concrete and perforated masonry
• General assembly, repair and maintenance where reliable universal plugs are needed

Key specifications

• Design: two-component universal plug with three anchoring functions (folding, expanding, knotting)
• Material compatibility: suitable for solid and hollow building materials including concrete, masonry, aerated concrete and plasterboard
• Performance: selected dimensions have European Technical Assessment (ETA) for concrete and masonry
• Available sizes (examples): 6 x 50 mm, 8 x 65 mm, 10 x 80 mm (larger anchorage depth for hollow materials)
• Pack quantity: 50 fasteners (screws/bolts included in this pack)

How to use

Drill a hole matching the plug diameter, clean the hole of dust, insert the DuoPower plug flush with the surface and drive the screw or bolt. During screw insertion the plug will fold, expand or form a knot depending on the substrate, creating the required anchorage. Ensure the screw length and diameter are appropriate for the chosen plug size and the thickness of the fixture.

Usage recommendations

For fixings in hollow building materials, aerated concrete and applications with bridge plaster choose the larger anchorage depth sizes such as 6 x 50 mm, 8 x 65 mm or 10 x 80 mm. Refer to the manufacturer’s load table and ETA details for safety-relevant installations in concrete and masonry.
