Expanding metal wall anchors are designed to hold heavy items by distributing the load across a larger area within the wall.

They are particularly useful in scenarios where traditional screws might loosen over time, such as in drywall installation or when hanging items from concrete surfaces.

Resin, on the other hand, plays a pivotal role in enhancing the stability of the bolt anchor. It is a two-part epoxy system consisting of a resin and a hardener. When mixed, they chemically react, forming a solid that can fill voids, bond surfaces, and strengthen the anchor's hold. Resin anchors offer advantages over mechanical anchors, particularly in situations where the substrate is weak or porous, or where vibration resistance is essential.
