How Bonded Fasteners Work

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.

In addition to their versatility, 5% self-drilling screws also offer excellent holding power. The self-drilling design creates a tight bond between the screw and the material, providing a secure connection that can withstand significant weight and pressure. This makes 5% self-drilling screws an excellent choice for projects that require a strong, reliable fastening solution.
