The Spring Toggle with Hook (widely known as a “Toggle Bolt Hook” or “Butterfly Anchor”) is the ultimate heavy-duty fastener for suspending loads from hollow ceilings and cavity walls. Unlike standard expansion plugs that rely on friction, the Spring Toggle with Hook features spring-loaded metal wings that fold to pass through a drill hole and then snap open automatically inside the cavity, bridging the load across a large area of the board’s back surface.
Product Overview: Our Spring Toggle with Hook consists of a threaded C-hook rod, a hex nut, a wide washer, and a zinc-plated spring wing assembly. It is the preferred choice for electricians and decorators for hanging chandeliers, hanging baskets, and suspended signage from gypsum board or lath-and-plaster ceilings.

Engineering Insight: Why is it best for Ceilings?
The Spring Toggle with Hook outperforms all other anchors in overhead applications:
- Wing Span: Once opened, the metal wings span approximately 50mm-80mm. This wide footprint prevents the anchor from ripping through the fragile drywall paper, allowing it to hold significantly more weight (often 10kg-20kg+) than a Molly bolt.
- Cavity Depth: Because the wings flip open using a spring, they require less cavity depth than “Gravity Toggles,” making them suitable for shallow ceiling voids filled with insulation.
For more details on toggle mechanisms, please refer to the Toggle bolt entry on Wikipedia.
Installation Guide
- Drill: Drill a hole large enough for the folded wings to pass through (usually 10mm-14mm).
- Assemble: Thread the nut and washer onto the hook bolt, then screw on the toggle wings just a few turns (ensure the wings fold towards the hook).
- Insert: Fold the wings flat against the bolt and push the entire assembly through the hole into the ceiling cavity.
- Snap: You will hear a “snap” or feel the wings spring open inside the ceiling. Pull back on the hook to engage the wings against the drywall.
- Tighten: While pulling down on the hook, spin the Hex Nut and washer up until they are tight against the ceiling face. This locks the hook in place.
Frequently Asked Questions (FAQ)
Q: What happens if I unscrew the hook?
A: WARNING: Never unscrew the hook completely after installation. If you do, the wings inside the ceiling will fall off and be lost forever in the void. You must install the full assembly at once.
Q: How much weight can an M5 toggle hold?
A: In 12.5mm standard drywall, a safe working load is typically around 10-15kg vertically. In stronger materials like plywood or lathe, it can hold much more.
