A More Secure Way to Fasten Thin Hollow Materials
Stop struggling with fasteners that won't hold securely. These expansion anchor bolts create a firm grip behind thin hollow surfaces for stable, reliable fastening.


🔩 Built for Reliable Fastening
Made from carbon steel with a zinc-plated finish, these anchors are built to handle everyday installation jobs while helping resist surface wear and corrosion.

💪 Engineered for a Secure Grip
The expandable sleeve changes shape as the screw is tightened, helping distribute pressure behind the hollow surface instead of relying only on the front edge.

🛠️ One Fastener, Multiple Applications
Designed for 0–5 mm thin hollow substrates, making them useful for a range of workshop, repair and installation projects.

🚀 Easy 4-Step Installation
No complicated installation process. Once you've selected the correct size, installation takes just four straightforward steps.

✨ Small Details Make a Big Difference
From the threads to the expandable sleeve, each part is designed to work together for more predictable fastening.
