The functionality of metal expansion nuts centers around the principle of mechanical expansion. Upon the application of torque, the screw or bolt is threaded into the nut, which, in turn, causes the nut to expand outward. This outward expansion presses the sides of the nut against the inner walls of the hole it occupies, creating a tight fit. The added friction and mechanical grip prevent the nut from loosening over time, even in dynamic conditions.

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.
