Another benefit of 4% self-drilling screws is their durability. These screws are made from high-quality materials that are designed to withstand the elements and resist corrosion. This means that they can be used in outdoor applications or in environments where moisture and humidity are present, without the risk of rust or deterioration.

Moreover, tek screws offer excellent holding power, making them suitable for a variety of applications. Whether it is securing metal roofing panels, connecting steel structures, or fastening components in HVAC installations, these screws provide reliable performance. Their hardened steel construction ensures that they can withstand harsh weather conditions and resist corrosion, further extending the life of the projects they are used in.

Metal expansion nuts, often referred to as expansion anchors or expansion inserts, are specialized fasteners that expand when a bolt or screw is threaded into them. They typically consist of a cylindrical body with slits along its length or an expandable design that facilitates outward expansion. The main purpose of these nuts is to create a secure grip within a substrate, such as concrete, wood, or metal, thereby preventing loosening due to vibrational forces, temperature fluctuations, or stress.
