3. Outdoor Furniture and Equipment With their resistance to rust, galvanized screws are a go-to choice for outdoor furniture assembly and other exposed applications.
4. Economical Solution Although they may have a higher upfront cost compared to standard fasteners, their performance and reliability translate to savings in the long term, minimizing the risk of structural failures.
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.
Once the concrete has cured, the nuts are tightened, securing the structure to the foundation Once the concrete has cured, the nuts are tightened, securing the structure to the foundationfoundation bolt fixing.
