A toggle bolt anchor is suitable for which type of base material?

• A. Wood
• B. Metal
• C. Drywall and hollow concrete/masonry
• D. Glass

Answer: (C)

A toggle bolt anchor is specifically designed for use in hollow or lightweight materials, making it highly effective for installation in drywall and hollow concrete or masonry. The anchor works by expanding behind the wall or hollow element, distributing the load over a larger area and preventing the anchor from pulling through the material.

In the case of drywall, which is often used in interior construction, the hollow nature allows the toggle mechanism to securely grip once it is pushed through the surface. Similarly, in hollow concrete or masonry, the toggle bolt's design allows it to anchor itself securely within the cavity, providing strength and stability for hanging objects.

Other materials like wood or metal do not require such specialized anchors since they can typically accommodate screws or more direct fastening methods without the risk of failure. Glass is also unsuitable for toggle bolts, as it requires specific fastening methods to prevent breaking or cracking during installation. Therefore, the most appropriate choice for toggle bolt anchors is indeed drywall and hollow concrete or masonry.
