What anchors are suitable for hollow materials?

The most suitable anchors for hollow materials are toggle bolts. These anchors are designed specifically to create a secure hold in hollow surfaces, such as walls made of drywall or hollow concrete blocks. Toggle bolts feature a unique design where they use a spring-loaded wing that opens up once it passes through the wall, providing a larger surface area that distributes the load across the back of the material. This feature allows toggle bolts to support heavier loads than standard screws or anchors would be able to manage in hollow sections.

In contrast, other types of anchors, such as stud bolt anchors, lag screws, and drive pins, rely on solid materials or sheathing to anchor effectively. For instance, lag screws are intended for use in solid materials, and while drive pins can work with specific masonry applications, they are not designed for hollow structures. Therefore, toggle bolts clearly stand out as the best option for securing items to hollow materials.
