Expandable anchors, often known as expansion anchors, are fasteners designed to secure objects to solid materials such as concrete, brick, or stone. The fundamental principle behind their design is the ability to expand under pressure, thereby creating a secure grip within the base material. When installed, the anchor's body expands outward, locking itself firmly in place, making it suitable for heavy loads and dynamic forces.

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.
