Wall plugs

Wall plugs provide a secure anchor point for screws in materials that are too brittle or soft to hold fasteners on their own. Used widely across interior and exterior jobs, they’re essential when fixing into masonry, concrete, brick, or plasterboard. You'll see them used in joinery, electrical work, plumbing, and heavy-duty installations such as radiators or frames.

This category includes plastic wall plugs in various formats, including red, yellow, and brown sizes for different screw gauges and base materials. Options range from basic expansion plugs to multi-purpose wall plugs with anti-rotation features. Universal wall plugs are also available, designed to suit mixed or unknown materials. Compared to frame fixings or resin anchors, wall plugs are lighter duty and quicker to install, making them better suited for medium-load tasks.

Wall plugs - FAQs

1. What are the differences between red, yellow, and brown wall plugs?

The different colours are for different gauges of screw. Red plugs suit 6–8 gauge screws, yellow are for 4–6 gauge, and brown are used with 10–14 gauge screws. Each is sized to fit typical UK drill bits and materials.

2. When should I use a universal wall plug over a standard one?

Use a universal wall plug when you're unsure of the substrate or working with mixed materials like thermalite or breeze blocks, where grip can be inconsistent.

3. Can wall plugs be reused after you’ve removed them?

It’s not recommended. Removal often damages the plug. For reliable holding power, it’s always best to use a new one.
