Sheet metal screws are specialized fasteners designed to join metal sheets together. They feature a sharp point and a thread that allows them to penetrate and grip metal surfaces securely. These screws can be used in various applications, including construction, automotive, and appliance manufacturing. Typically made from materials like stainless steel or zinc-plated steel, sheet metal screws are resistant to corrosion and provide durability. They come in various sizes and head types, such as flat, pan, or hex, making them versatile for different projects. Proper installation ensures a strong hold, making them essential in metalworking tasks.
