These screws are versatile and widely used for joining thin metal sheets, plastic, or wood. The self-tapping feature allows them to create internal threads as they are driven into the material, saving time and effort during installation. Their stainless steel construction ensures high resistance to environmental factors like rust and oxidation, making them suitable for indoor and outdoor use, including marine and humid environments. They are commonly employed in industries such as automotive, electrical, and home improvement projects where reliable and long-lasting fasteners are required.

History
Self-tapping screws have been used since the early 20th century to simplify fastening processes by eliminating the need for pre-drilled holes. The introduction of stainless steel as a material improved their durability and made them resistant to rust and environmental damage. Over the decades, innovations in screw head design, including the truss head, have enhanced their usability by providing a larger bearing surface and reducing the risk of material deformation during installation.
