2. Strong and Secure Fastening The hexagonal head design provides a larger surface area for torque, allowing for a secure grip during installation. This results in strong fastening that withstands vibrations and environmental factors, making these screws ideal for outdoor and industrial applications where stability is essential.

Conclusion

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.
