This screws are a type of screws that undergo a special surface treatment to provide enhanced resistance against loosening, rusting, and preventing accidental dropping. They are typically made from carbon steel material and undergo a phosphating process, resulting in a black-colored appearance. The locking screws are commonly used in various applications where a secure and durable fastening solution is required, such as in machinery, automotive, construction, or industrial equipment. They offer improved performance and reliability in environments where vibration, corrosion, and accidental dropping may occur.
