A socket screw is a type of fastener characterized by a cylindrical head with a recessed drive, allowing it to be tightened or loosened using a specific tool, such as an Allen wrench or hex key. This design provides a secure grip and is often used in applications where space is limited, making it easier to access the screw. Socket screws are commonly made from various materials, including steel, stainless steel, and aluminum, depending on the required strength and corrosion resistance. They are widely used in industries such as automotive, electronics, and furniture assembly, where precision and reliability are essential.
