## Long description

The Koelner expansion plug set, featuring an 8mm diameter plug and a 5.0x50mm cross-recessed screw, provides a reliable and versatile fastening solution for a wide range of construction and renovation projects.

Advantages
This expansion plug system is characterized by its high-quality construction, which facilitates a firm grip within the substrate to prevent loosening over time. The cross-recessed screw head is specifically designed to work seamlessly with standard screwdrivers or power tools, allowing for quick and efficient installation without the risk of slippage.

The universal nature of these plugs makes them a dependable choice for everyday mounting needs.
Suitable for
Mounting shelves and wall cabinets
Installing lighting fixtures and electrical accessories
Securing baseboards and decorative moldings
General household repairs and maintenance
This product may not be suitable for use in highly porous or crumbling materials where a standard expansion plug cannot achieve sufficient friction. It is also not intended for heavy-duty structural load-bearing applications in concrete or masonry that require specialized chemical anchors or heavy-duty metal expansion bolts.
Key specifications
Plug diameter: 8mm
Screw dimensions: 5.0mm x 50mm
Head type: Cross-recessed
Quantity: 200 pieces
To use these expansion plugs, first drill a hole into the base material using an 8mm masonry drill bit. Ensure the hole is cleaned of dust and debris to allow for a proper fit. Insert the expansion plug into the hole until it is flush with the surface. Place the object you wish to mount over the hole, insert the screw, and tighten it using a compatible cross-recessed screwdriver until the plug expands and locks securely into the wall.
What to consider before purchase
Verify the thickness of the material you are mounting to ensure the 50mm screw length is appropriate.
Check the compatibility of the plug with your specific wall type, such as solid brick, concrete, or hollow blocks.
Ensure you have the correct drill bit size for an 8mm plug.
For optimal performance, always ensure the drill hole is the correct depth and diameter. Avoid over-tightening the screw, as this may compromise the integrity of the plug's expansion within the wall.
