A sheet metal screw is a type of fastener designed specifically for joining metal sheets together. It features a sharp point that allows it to penetrate metal surfaces easily, and its threads are designed to grip the material 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 and ensuring a secure fit in various materials.
