What is a key difference between a bonded anchor and a mechanical anchor?

A bonded anchor relies on chemical adhesion, which sets it apart from mechanical anchors. When a bonded anchor is installed, an adhesive is used to secure the anchor into the base material, creating a strong bond as the adhesive cures. This chemical connection helps to distribute loads effectively and can enhance the strength of the anchor in various materials, including concrete and masonry.

In contrast, mechanical anchors function based on physical expansion or interlocking mechanisms. They physically grip the base material rather than relying on adhesive properties. This fundamental difference in how the anchors obtain their holding strength is why chemical adhesion is a significant characteristic of bonded anchors, making option B the correct choice. Understanding this distinction is crucial for selecting the appropriate anchor type for specific applications and materials, ensuring optimal performance and safety in anchor installations.
