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.

In addition to their functional benefits, self-drilling trim screws also offer advantages in terms of cost-effectiveness and productivity. By combining two steps into one, they significantly reduce labor costs and increase project efficiency By combining two steps into one, they significantly reduce labor costs and increase project efficiency By combining two steps into one, they significantly reduce labor costs and increase project efficiency By combining two steps into one, they significantly reduce labor costs and increase project efficiencyself drilling trim screws. Moreover, their durability and resistance to corrosion, often thanks to a zinc-plated or stainless steel coating, ensure a long-lasting and reliable hold.
