A toggle bolt, also known as a toggle anchor, is a type of fastener used to secure objects to hollow walls, ceilings, or other surfaces where there is no solid backing or stud behind the surface material. It is designed to provide a secure and reliable anchor point for hanging heavy items.

A toggle bolt consists of two main components: a spring-loaded metal wing and a threaded bolt. The metal wing is folded flat and inserted through a pre-drilled hole in the surface. Once inside the hollow space behind the surface, the wing springs open, creating a secure hold. The threaded bolt is then inserted into the metal wing and tightened to provide additional support.

The advantage of a toggle bolt is its ability to distribute weight over a larger area, increasing the load-bearing capacity compared to standard screws or nails. This makes it suitable for hanging items such as shelves, mirrors, light fixtures, or other heavy objects on walls or ceilings.

Toggle bolts come in various sizes and weight ratings, so it's important to choose the appropriate size and weight capacity for your specific application. Always follow the manufacturer's instructions and guidelines when installing toggle bolts to ensure proper usage and maximum holding strength.
