- Design Flexibility Various bracing options enable architects and engineers to create aesthetically pleasing designs while maintaining the necessary structural performance.

In addition to their pointed tips, self-drilling screws often come with various coatings, such as zinc plating or ceramic finishes, which enhance their resistance to rust and environmental elements. These coatings not only extend the lifespan of the screws but also improve their aesthetic appeal, making them suitable for visible applications.

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.
