A wall plug, also known as a rawl plug or anchor plug, is a device used to secure screws or fasteners into materials like brick, concrete, or drywall. It provides a stable anchor when drilling into surfaces that can't hold screws directly, like hollow or soft walls.

Key Features:

• Prevents loosening: Expands inside the hole to grip the material tightly.
• Material options: Available in plastic, nylon, metal, or other materials depending on the weight and purpose.
• Versatile: Ideal for use in construction, home improvement, and electrical work.

Wall plugs are typically used with screws to install items like shelves, hooks, or light fixtures securely into walls.
