Headless screws are fasteners that do not have a visible head, making them ideal for applications where a smooth surface is desired. They are typically installed using a special tool that engages with a recess in the screw's body, allowing for a clean and unobtrusive finish. These screws are commonly used in furniture assembly, electronics, and automotive applications. Their design helps prevent tampering and provides a sleek appearance, making them popular in modern design. Headless screws can be made from various materials, including stainless steel and plastic, to suit different environments and requirements.
