A toggle is also known as a butterfly anchor, used for hanging things on hollow walls such as drywall. Toggles have wings that open inside a hollow wall, bracing against it to hold the fastener securely. The wings, once fully opened, greatly expand the surface area making contact with the back of the hollow wall. This ultimately spreads out the weight of the secured item, increasing the weight that can be secured compared to a regular bolt.
