Koelner TM-08 Brass Expansion Anchor M8, 10x30mm, 100 pieces

The Koelner TM-08 brass expansion anchor is a professional-grade fastening solution engineered for high-performance anchoring in solid construction materials. With an M8 internal thread and a compact 10x30mm design, this anchor utilizes a specialized expansion mechanism that ensures a firm and lasting grip within the substrate. Its brass construction offers inherent resistance to corrosion, making it a reliable choice for both indoor and outdoor installations where durability is essential.

Advantages

The primary benefit of the Koelner TM-08 is its robust brass composition, which provides superior longevity and resistance to environmental factors compared to standard steel anchors. The internal thread design allows for the use of various metric bolts, offering flexibility in mounting different fixtures. Its compact size ensures it can be used in tight spaces while still providing the necessary holding power for demanding professional construction and renovation tasks.

Suitable for

• Fastening fixtures into solid concrete and stone
• Securing heavy-duty components in masonry
• Professional construction and renovation projects
• Applications requiring corrosion-resistant hardware

When it may not be suitable

This anchor is not intended for use in hollow materials such as drywall, hollow bricks, or aerated concrete, as it requires a solid substrate to achieve proper expansion and grip. It is also not recommended for overhead applications involving extreme vibration or dynamic loads that exceed the technical capacity of an M8 brass anchor.

Key specifications

• Material: Brass
• Internal thread: M8
• Anchor diameter: 10 mm
• Anchor length: 30 mm
• Quantity: 100 pieces

How to use

To install the Koelner TM-08, first drill a hole into the solid substrate using a drill bit that matches the diameter of the anchor. Ensure the hole is cleaned of dust and debris to allow for optimal expansion. Insert the anchor into the hole until it is flush with the surface. Once positioned, insert the corresponding M8 bolt through the fixture and tighten it into the anchor. As the bolt is tightened, the brass body expands, locking the anchor securely into the material.

What to consider before purchase

• Verify that the substrate is solid concrete or stone
• Ensure the M8 bolt length is compatible with the fixture thickness
• Check the load-bearing requirements of your specific application

Usage recommendations

For the best results, always ensure the drill hole depth is slightly deeper than the anchor length to accommodate any residual dust and ensure the bolt can be fully seated.
