A one-way screw is a type of screw designed to be tightened but not easily loosened. It has a special head that can only be turned in one direction, usually for security purposes. Once the screw is installed, it is difficult to remove without damaging the head, making it useful in places where tampering or theft is a concern. One-way screws are often used in public fixtures, equipment, or machinery to prevent unauthorized access or adjustments.
