## Long description

The Koelner expansion plug set consists of 200 high-quality 6mm diameter plugs paired with 4.0x50mm cross-recessed screws. This comprehensive kit is engineered for dependable fastening in solid construction materials, providing a stable and secure anchor for a wide range of mounting applications. The inclusion of cross-recessed screws allows for efficient installation using standard manual screwdrivers or compatible power tools, ensuring a professional finish for both construction sites and residential DIY projects.
Advantages
These expansion plugs are designed to offer superior grip and stability within solid substrates, minimizing the risk of rotation or pull-out during installation. The durable material composition ensures long-term reliability, while the precision-engineered thread of the included screws facilitates smooth driving and optimal expansion of the plug. By providing a complete set of matching components, this product eliminates the need for sourcing separate fasteners, thereby streamlining the workflow and ensuring compatibility between the plug and the screw.
Suitable for
Mounting shelves and wall cabinets
Installing lighting fixtures and electrical accessories
Securing decorative elements to solid walls
General home improvement and renovation tasks
This product is not intended for use in hollow bricks, aerated concrete, or soft insulation materials, as the expansion mechanism requires a solid base to function correctly. It is also not recommended for heavy-duty structural load-bearing applications where specialized anchors are required.
Key specifications
Plug diameter: 6 mm
Screw dimensions: 4.0 mm x 50 mm
Drive type: Cross-recessed
Quantity: 200 pieces
Application: Solid building materials
To use these expansion plugs, first drill a hole into the solid substrate using a 6mm masonry drill bit, ensuring the hole depth is slightly greater than the length of the plug. Clear any debris or dust from the hole to ensure a proper fit. Insert the plug into the hole until it is flush with the surface. Position the item to be mounted, insert the screw through the fixture and into the plug, and tighten using a compatible screwdriver or power tool until the screw is firmly seated.
What to consider before purchase
Verify that the substrate is a solid material such as concrete or solid brick
Ensure the drill bit diameter matches the plug size
Check the required screw length for the thickness of the material being mounted
For optimal performance, always ensure the drill hole is clean and free of dust before inserting the plug. Do not overtighten the screw, as this may compromise the integrity of the expansion within the wall.
