Self-tapping screws are made from high-strength materials, originally designed to handle a variety of materials, including metal, plastic, and wood. The ability to penetrate and form threads in the base material makes hex head self-tapping screws particularly useful for applications where traditional screws may fail or require additional components for anchoring.

In the automotive sector, self-drilling screws are utilized for assembling various components, ensuring that parts stay securely fastened despite vibrations and shifting. Similarly, in HVAC systems, they secure ducts and other metal components, contributing to the overall efficiency and stability of the installation.
