## Long description

The Koelner KD-10120 expansion plug is a professional-grade fastening solution designed for reliable anchoring in a variety of construction materials.

This set of 25 pieces is engineered to meet the demands of both professional contractors and DIY enthusiasts working on renovation or structural assembly projects.
Advantages
The primary benefit of the Koelner KD-10120 is its long expansion zone, which distributes pressure effectively across a larger surface area within the hole, significantly increasing pull-out resistance. The inclusion of a durable hexagonal head screw allows for high torque application, ensuring that the fastener remains securely in place even under heavy loads. The design is optimized for versatility, allowing it to perform consistently across different types of masonry and concrete, making it a dependable choice for demanding structural tasks.
Suitable for

Installing structural steel components

General construction and renovation anchoring tasks
When it may not be suitable
This expansion plug is not intended for use in hollow materials or thin-walled substrates where the expansion mechanism cannot engage properly. It is also not recommended for overhead installations requiring specialized seismic-rated anchors or for applications involving highly corrosive environments without additional protective measures.

How to use
To install the Koelner KD-10120, first drill a hole into the substrate using a drill bit that matches the diameter of the plug. Ensure the hole is cleaned of dust and debris to allow for optimal expansion. Insert the plug into the hole until it is flush with the surface. Place the fixture over the hole, insert the hexagonal screw through the fixture into the plug, and tighten it using a suitable wrench or socket tool until the plug is fully expanded and the fixture is firmly secured.
What to consider before purchase
Verify the compatibility of the plug size with your specific substrate material
Ensure the drill bit diameter matches the plug requirements
Check the load-bearing requirements of your project against the fastener specifications
Confirm the total thickness of the material being fastened to ensure the screw length is sufficient
Usage recommendations
Always ensure the hole is drilled to the correct depth and diameter to guarantee the maximum expansion capacity of the plug. Using a clean, debris-free hole significantly improves the holding power of the anchor.
