    The Blackening Line starts with cleaning and acid washing to prepare the surface. Then, fasteners go through a chemical blackening process, where they are treated in a specialized solution to create a smooth, protective black oxide layer. After treatment, steps like rinsing, oiling, and drying ensure the fasteners are ready for use and built to last.
