Koelner KD-10120 Expansion Plug 10x120mm with Hexagonal Screw, 25 Pieces

The Koelner KD-10120 expansion plug is a professional-grade fastening solution designed for reliable anchoring in a variety of construction materials. Measuring 10x120mm, this plug features an extended expansion zone that ensures superior grip and stability within the substrate. Each unit is supplied with a high-quality hexagonal head screw, providing a robust connection that is easy to install using standard hand or power tools. 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

• Fastening heavy wooden elements to concrete walls
• Installing structural steel components
• Securing mounting brackets for heavy equipment
• 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.

Key specifications

• Plug diameter: 10 mm
• Plug length: 120 mm
• Screw type: Hexagonal head
• Material: High-quality plastic plug with steel screw
• Quantity: 25 pieces per package

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.
