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.

Tek screws serve as an essential component in modern cladding systems, providing strength, efficiency, and resistance to environmental factors. By understanding their characteristics, applications, and best practices, construction professionals can ensure a robust and reliable cladding installation, contributing to the longevity and performance of buildings. As construction technologies continue to evolve, Tek screws will likely remain a key player in the industry, facilitating faster and more effective building practices.
