Our high strength bolts after various processing, its tensile strength, high surface hardness, good mechanical properties. The surface treatment of bolts is recommended to adopt surface phosphating or surface oxidation, adopting high-tech environmental protection technology, and adopting self-developed new technology and new technology to continuously reduce the production cost of products, which has obvious advantages and competitiveness in quality and price!
