The 304 Countersunk Cross Self-tapping Screw is a high-quality fastening solution designed for securing materials without the need for pre-drilled holes. Made from durable 304 stainless steel, it offers excellent resistance to corrosion and oxidation, making it ideal for use in moist or corrosive environments such as marine, outdoor, and industrial applications. The countersunk design allows the screw to sit flush with the surface, providing a neat and clean appearance, while the cross drive ensures easy and secure fastening with common Phillips screwdrivers. This self-tapping feature cuts its own thread, simplifying installation and enhancing holding power.
