Material: Carbon steel
Hardness grades: 4.8, 8.8, 10.9, 12.9
Surface finishes: Plain / natural, blue-white zinc plated, yellow zinc plated, hot-dip galvanized, tempered blackened, Dacromet
High-strength Dacromet coated threaded rod. Using the Dacromet process, a uniform protective film is formed on the surface, providing excellent corrosion resistance, rust resistance, and high/low temperature tolerance, with no risk of hydrogen embrittlement and no damage to the substrate's inherent strength. Suitable for complex environments such as high temperature, high humidity, and strong corrosion, including automotive components, marine equipment, precision machinery, and similar applications. Stable and reliable performance.
