Self Tapping Screws are designed to create their own threads when driven into pre-drilled holes in metal, wood, or plastic. They eliminate the need for tapping tools, making them highly convenient for quick assembly. These screws are widely used in construction, furniture, automotive, and sheet metal applications due to their secure and vibration-resistant fastening.
