High-strength yellow zinc plated hex socket head cap screw. Treated with electroplated zinc plus yellow passivation, resulting in a uniform and attractive surface finish that offers both corrosion resistance and decorative appeal. Rust resistance is superior to blue-white zinc plating, with good coating toughness and no peeling. The hex socket design allows for concealed installation. Suitable for applications requiring both aesthetics and corrosion resistance, such as machinery components, automotive parts, and household appliance assembly.
