Koelner Interset M5x40mm Metal Cavity Anchor, 100 pieces

The Koelner Interset M5x40mm metal cavity anchor is a professional-grade fastening solution engineered for secure installation in hollow base materials. This anchor is specifically designed to provide reliable support when mounting objects to plasterboard, gypsum fiberboards, and other hollow wall structures. With a pack size of 100 pieces, it offers a comprehensive supply for both large-scale construction projects and smaller home improvement tasks, ensuring that fixtures remain stable and firmly attached over time.

Advantages

The primary benefit of the Koelner Interset anchor lies in its robust metal construction, which provides superior strength compared to plastic alternatives. The design facilitates controlled expansion behind the wall surface, creating a wide bearing area that effectively distributes the load. This mechanism prevents damage to the substrate and ensures a high pull-out resistance, making it a dependable choice for heavy-duty interior applications. Its ease of installation allows for efficient workflow, reducing the time required for mounting various interior elements.

Suitable for

• Mounting shelves and wall cabinets
• Installing lighting fixtures and lamps
• Attaching mirrors and decorative wall elements
• Securing curtain rails and blinds
• Fastening electrical conduits and cable trays

This anchor may not be suitable for use in solid masonry, concrete, or dense stone materials, as its expansion mechanism is specifically calibrated for hollow cavities. It is also not recommended for overhead applications involving heavy dynamic loads or structural support requirements where specific building codes mandate different types of anchors.

Key specifications

• Anchor diameter: M5
• Anchor length: 40 mm
• Material: Zinc-plated steel
• Application: Hollow wall materials
• Quantity: 100 pieces

To use the Koelner Interset anchor, first drill a hole in the target material with the appropriate diameter. Insert the anchor into the hole until the flange sits flush against the surface. Use a dedicated setting tool or a manual screwdriver to tighten the screw, which will cause the metal legs to expand and grip the rear side of the wall. Once the anchor is fully expanded and secure, the screw can be removed to attach the desired fixture, then re-inserted and tightened to complete the installation.

What to consider before purchase

• Verify the thickness of the hollow wall material to ensure compatibility with the 40mm length.
• Check the weight of the object to be mounted to ensure it falls within the load-bearing capacity of an M5 anchor.
• Ensure you have the correct drill bit size for the anchor diameter.
• Consider using a professional setting tool for faster and more consistent installation results.

For optimal performance, always ensure the anchor is fully expanded behind the wall before applying the final load. Avoid over-tightening, as this may damage the integrity of the plasterboard or the anchor itself.
