What are wall anchors and how are they used in home improvement projects?

Wall anchors are devices used to secure objects to walls that may not be able to support the weight on their own. They are commonly used in home improvement projects to hang heavy items such as shelves, mirrors, or artwork. Wall anchors are inserted into the wall and provide additional support for the screws or nails used to hang the object, helping to prevent damage to the wall and ensuring the object stays securely in place.
