What is a toggle bolt primarily used for?

A toggle bolt is specifically designed for anchoring items in hollow spaces, making it ideal for use with materials like drywall. When installed, the toggle mechanism will spread the load over a larger area by using wings that open up after the bolt passes through the wall. This allows it to create a secure hold even when the wall itself does not have a strong structure, such as in hollow drywall or masonry.

Toggle bolts are particularly useful for hanging heavier objects or fixtures that require firm support, making them a preferred choice when dealing with walls that lack solid backing. The capacity to anchor in hollow spaces is what differentiates toggle bolts from other types of anchors.
