self drilling metal anchor

Another benefit of self-drilling screws is their resistance to corrosion. Many self-drilling screws are coated with materials such as zinc or stainless steel to protect them from rust and corrosion. This is particularly important when working with heavy steel components that are exposed to harsh weather conditions or corrosive environments. The corrosion-resistant coating ensures the longevity of the screws and helps maintain the integrity of the structures they are holding together.

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.
