Types Of Wall Plugs
Wall plugs help fix screws into different wall materials. They provide support and prevent screws from loosening. Choosing the right wall plug is important for strong and safe fittings.
There are several types of wall plugs. Each type works best with certain materials and loads. Here, we explain four common types of wall plugs.
Plastic Anchors
Plastic anchors are the most common type. They are easy to use and work well with drywall, plaster, and brick. The anchor expands when you insert the screw, holding it tight in the wall.
Metal Anchors
Metal anchors are stronger than plastic ones. They are best for heavy items and solid walls like concrete or stone. Metal anchors resist bending and provide a firm grip.
Toggle Bolts
Toggle bolts have wings that open inside a hollow wall. They spread the load over a large area. This makes them perfect for hanging heavy objects on drywall or hollow walls.
- Insert the folded toggle bolt through the hole
- Wings open inside the wall cavity
- Tighten the screw to secure the bolt
- Supports heavy loads on hollow walls
Molly Bolts
| Feature | Description |
| Material | Metal with expandable sleeves |
| Use | Hollow walls and drywall |
| Installation | Insert then tighten to expand sleeves |

Connecting Wires To The Plug
Identify each wire by its color before connecting. Usually, brown is live, blue is neutral, and green/yellow is ground.
| Wire Color | Function | Plug Terminal |
| Brown | Live | L |
| Blue | Neutral | N |
| Green/Yellow | Earth | E or Ground |
Loosen the screws on the plug terminals. Insert each wire fully and tighten the screws firmly.
Securing The Connection
Ensure that wires do not move inside the plug. Use the clamp to hold the cable in place.
Follow these tips to secure the connection:
- Check that no copper is outside the terminal.
- Make sure the cable grip holds the outer sheath only.
- Tighten all screws but do not over-tighten to avoid damage.
- Test the plug by gently pulling the wires to confirm they are secure.
Safety Precautions
