Koelner KMW-06040 Metal Hammer-In Plug 6x40mm, 100 pieces

The Koelner KMW-06040 metal hammer-in plug is a professional-grade fastening solution engineered for rapid and secure installation in solid substrates. Measuring 6x40 mm, this fastener is specifically designed to provide high load-bearing capacity and structural integrity in demanding construction environments. Its all-metal construction offers superior durability and inherent fire resistance, making it a dependable choice for critical mounting tasks where safety and longevity are paramount.

Advantages

The primary benefit of the Koelner metal hammer-in plug is its efficient installation process, which significantly reduces labor time on site. By utilizing a simple hammer-in mechanism, the plug expands firmly within the substrate to create a permanent, high-strength anchor. The robust metal composition ensures that the fastener maintains its integrity under stress and high temperatures, providing a level of reliability that plastic alternatives cannot match. This makes it an essential component for professional contractors seeking consistent performance in solid masonry and concrete applications.

Suitable for

• Fastening steel profiles and brackets to concrete
• Mounting fire-rated installations
• Securing heavy-duty fixtures in solid masonry
• Professional construction and renovation projects

When it may not be suitable

This metal hammer-in plug is not intended for use in hollow bricks, aerated concrete, or soft materials where the expansion mechanism cannot achieve a secure grip. It is also not recommended for applications requiring vibration resistance or in environments where the substrate is prone to crumbling.

Key specifications

• Diameter: 6 mm
• Length: 40 mm
• Material: High-quality metal
• Installation type: Hammer-in
• Quantity: 100 pieces per pack

How to use

To install the Koelner KMW-06040, first drill a hole into the solid base material using a drill bit that matches the diameter of the plug. Ensure the hole is cleaned of dust and debris to allow for proper expansion. Insert the plug through the fixture and into the hole. Use a hammer to drive the internal pin flush with the head of the plug, which will trigger the expansion mechanism and lock the fastener securely into the substrate.

What to consider before purchase

• Verify that the substrate is solid concrete or dense stone
• Ensure the drill bit size matches the plug diameter
• Check the required load capacity for your specific application
• Confirm the thickness of the material being fastened

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses, when drilling and hammering. Ensure the drill hole depth is slightly deeper than the length of the plug to accommodate any residual dust.
