The Environmentally Friendly Trivalent Color Hexagonal Flange Nut represents a significant advancement in fastening technology, combining robust functionality with ecological responsibility. This nut is treated with a trivalent chromate finish that provides excellent corrosion resistance without the environmental and health hazards associated with hexavalent chromium finishes. The integrated flange offers a broader bearing surface, which distributes the load evenly and eliminates the need for an additional washer.
