This blue and white zinc-coated cross-head self-tapping screw is a multifunctional fastener that combines efficient construction with corrosion resistance and aesthetic appearance. Its surface is treated with blue and white zinc, which gives it a bright and corrosion-resistant finish. The cross-head (flat-topped) design ensures that the head of the screw is flat and does not protrude after installation. The unique self-tapping drill tip allows it to drill and tap holes in metal thin plates, color steel plates, and other materials, significantly saving the pre-drilling process and enhancing installation efficiency. The trapezoidal thread further enhances the holding strength in wood or composite materials. This product supports comprehensive customization in size, length, and material to meet the specific requirements of different projects for specifications, strength, and weather resistance. It is suitable for the installation of steel structures, color steel roofs, fences, and outdoor facilities, making it a reliable choice in the fields of metal processing, construction, and maintenance.
