Nail expansion anchors are fasteners that consist of a metal sleeve and a nail or shank. When installed into a pre-drilled hole, the anchor expands against the wall of the hole, creating a stronghold that keeps the anchor firmly in place. The simple design makes them suitable for a range of applications, from hanging shelves to securing heavier equipment.

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.

Conclusion

- Ease of Use Their installation is relatively quick and uncomplicated, even for users with limited experience.
