Screw & wall plug kit Fischer 522724

The Fischer 522724 frame fixing kit is a professional-grade solution designed for secure anchoring in various building materials. This set includes 50 high-quality plastic wall plugs and matching zinc-plated steel hexagon head screws with integrated TX40 bit holders. Engineered for versatility, these fixings feature two distinct expansion zones that ensure reliable hold in solid, hollow, and aerated masonry, providing a stable connection for non-load-bearing systems.

Advantages

The primary benefit of this system is its long expansion element, which allows for multiple anchorage depths of 50, 70, and 90 mm, making it highly adaptable to different wall types. The unique geometry of the plug ensures that retention forces are distributed evenly throughout the drill hole, minimizing the risk of material damage. Furthermore, the inclusion of longer ribs prevents the plug from rotating during the installation process, even when setting the anchor deep into the substrate. Its approval for single-point fixing in cracked concrete offers a reliable alternative to traditional steel anchors for specific outdoor applications.

Suitable for

• Façade substructures
• Ceiling and roof substructures
• Installation of awning roofs
• Outdoor railings
• Fixing into concrete, brick, and aerated concrete

When it may not be suitable

This kit is specifically designed for non-load-bearing systems and should not be used for structural applications requiring high-load capacity beyond the manufacturer's specifications. It is not intended for use in materials that cannot support the expansion force of the plug, such as highly friable or crumbling substrates.

Key specifications

• Plug diameter: 10 mm
• Plug length: 160 mm
• Material: Durable plastic plug with zinc-plated steel screw
• Drive type: TX40
• Anchorage depths: 50 mm, 70 mm, 90 mm
• Quantity: 50 pieces

How to use

To install, drill a hole with a 10 mm diameter to the required depth. Clean the drill hole thoroughly to ensure optimal expansion. Insert the plug into the hole until it is flush with the surface. Place the component to be fixed over the hole and drive the screw in using a TX40 bit. The screw will expand the plug, creating a secure mechanical bond within the building material.

What to consider before purchase

• Verify the thickness of the material being attached to ensure the 160 mm length is sufficient.
• Check the substrate type to ensure compatibility with the expansion zones of the plug.
• Ensure you have a compatible TX40 screwdriver or bit for installation.

Usage recommendations: Always ensure the drill hole is free of dust and debris before insertion to maintain maximum pull-out resistance. For optimal performance in aerated concrete, ensure the drill hole is not oversized.
