Self-drilling anchors are designed with a screw point and cutting edges that allow them to cut through various substrates, including rock, concrete, and steel. They also have a thread section that allows for immediate load transfer after installation, providing immediate stability to the structure. This feature is invaluable in situations where immediate support is required, such as in slope stabilization, foundation repair, or even in temporary works during construction.

Perhaps one of the most significant benefits of resin anchors is their durability. Unlike other types of anchors, such as expansion anchors, which rely on mechanical forces to secure the bolt, resin anchors create a chemical bond with the concrete, providing a more reliable and long-lasting connection. This makes them an excellent choice for applications where the anchor must withstand heavy loads or extreme weather conditions over an extended period.

Expanding metal wall anchors are designed to hold heavy items by distributing the load across a larger area within the wall. They typically consist of a metal sleeve that expands when a screw is driven into it. This expansion action grips the surrounding material, creating a solid anchor point that can support significant weight. 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.
