Features of Butterfly Wall Plugs

Butterfly wall plugs, also known as **butterfly anchors** or **toggle wings**, are a type of wall fastener designed to provide a secure hold in hollow walls, such as drywall, plasterboard, or other thin materials. They are ideal for hanging medium-weight objects like mirrors, shelves, or light fixtures.

Features of Butterfly Wall Plugs:

1. **Design:**  

   - Made of durable plastic (nylon or polypropylene) or metal (zinc, steel).  

   - Consists of two hinged wings that expand behind the wall when the screw is tightened.  

   - The wings fold flat for easy insertion and then spring open inside the cavity for a secure grip.

2. **Types:**  

   - **Plastic Butterfly Anchors:** Light-duty use, suitable for drywall or hollow-core doors.  

   - **Metal Butterfly Toggles:** Heavy-duty anchoring, often used for heavier loads in drywall or plaster.  

3. **Load Capacity:**  

   - Plastic versions typically hold **10–25 kg (22–55 lbs)** depending on wall thickness.  

   - Metal toggle versions can support **25–50 kg (55–110 lbs)** or more.  

4. **Installation:**  

   - Requires a pre-drilled hole (size varies by model, usually **8–14 mm**).  

   - Insert the folded plug into the hole, then tighten the screw to expand the wings behind the wall.  

   - The wings press against the back of the wall, distributing weight evenly.  

5. **Advantages:**  

   - Strong hold in hollow walls.  

   - Easy to install and remove if needed.  

   - Reusable in some metal toggle designs.  

6. **Disadvantages:**  

   - Not suitable for solid walls (brick, concrete).  

   - Requires sufficient wall cavity depth for wings to open.  

*Common Uses:**  

- Hanging shelves, mirrors, or artwork.  

- Mounting TVs (with proper weight rating).  

- Securing curtain rods or light fixtures.  

 **Installation Steps:**  

1. **Drill a hole** slightly larger than the plug.  

2. **Insert the folded butterfly plug** into the hole.  

3. **Push until wings open** behind the wall.  

4. **Tighten the screw** to secure the anchor in place.  

Butterfly wall plugs are a versatile and reliable solution for hollow-wall anchoring, offering a balance between ease of use and strong holding power.
