7 Reasons These Anchors Stand Out
1. Create a Grip Where a Normal Screw Can’t
When you’re working with thin or hollow material, there’s often very little for a regular screw to grab. These expansion anchors open behind the surface as they’re tightened, creating a broader mechanical grip where you need it.
2. Expand Behind the Surface
A standard screw relies on the material around the hole. These anchors work differently. Once inserted, the sleeve expands behind the material as the screw is tightened helping create a secure fastening point without needing access to the backside.
3. Built From Heavy-Duty Carbon Steel
Constructed from carbon steel with a plated finish, these anchors are designed to provide a durable fastening solution for repairs, installations and DIY projects. The metal construction gives you a more substantial alternative to basic plastic anchors for suitable applications.
4. Works With Thin & Hollow Materials
These anchors are designed for suitable thin and hollow substrates where conventional screws may struggle to get enough grip.
Use them for compatible:
- Thin metal panels
- Hollow sections
- Boards and panels
- Selected drywall applications
- DIY and repair projects
5. Install in Just a FewSimple Steps
Drill. Insert. Tighten. Secure.Installation doesn’t require a complicated fastening system.
6. Choose the Size That Fits Your Project
Three Sizes for Different Jobs
Available in:
- M4 × 20:8 mm recommended hole
- M5 × 25:10 mm recommended hole
- M6 × 25:12 mm recommended hole
7. No Access Behind the Material Required
Working inside a cabinet, behind a panel or on a hollow section can make conventional fastening difficult. These expansion anchors are inserted from the accessible side and create their grip behind the material as you tighten them.
That means you can create a threaded fastening point without needing to hold a nut behind the surface.
