Screw & wall plug kit Fischer 541109 75 pcs Plastic for various materials

The Fischer screw and wall plug kit (Fischer 541109) contains 75 plastic anchors designed for reliable fixings in a range of substrates including autoclaved aerated concrete, brick, concrete, gypsum block, gypsum fibre board and plasterboard. The DuoPower plugs combine two component materials to adapt to different substrates, delivering solid load values and consistent performance for construction and DIY installations.

Advantages

The two-component design provides high load capacity and adapts its function depending on the substrate. The plug gives clear tactile feedback when it is seated correctly, allowing precise installation. Short plug length enables faster fixing without deep drilling, while the narrow rim prevents the plug from slipping into the drill hole. Serrated anti-rotation ribs stop the plug from turning during installation. Longer anchorage depth in sizes 6 x 50, 8 x 65 and 10 x 80 improves performance in hollow building materials, autoclaved aerated concrete and when bridging plaster.

Suitable for

• Autoclaved aerated concrete (AAC)
• Brick and solid masonry
• Concrete
• Gypsum block and gypsum fibre board
• Plasterboard and plastered surfaces

How to use

Choose a plug size suitable for the screw and the substrate. Drill the correct diameter hole to the required depth, clean out dust, insert the DuoPower plug until its rim sits flush with the surface, then drive the screw to achieve the required anchorage. Monitor tactile feedback from the plug to confirm proper seating and avoid over-tightening the screw to prevent damage to the substrate or plug.

Usage recommendations

Use the longer plug lengths (6 x 50, 8 x 65, 10 x 80) for hollow materials and when bridging plaster; select shorter plugs for thin boards or solid substrates. Always follow drill diameter and embedment depth guidance for the chosen plug and screw to ensure safe load capacity.
