Product details

In order to maximize the service life and maximize the function of the big on edge square nuts, the Square nuts(big on edge) will be specially treated to adapt to different special working environments.

Hot dip galvanizing coats big on edge square nuts with a thick layer of zinc for rust-proof properties and is ideal for outdoor or offshore applications. Electrogalvanizing provides a smoother surface for large indoor machinery, balancing corrosion resistance and aesthetics. The black oxide treatment provides a smooth, matte appearance while enhancing rust protection and reducing light reflection. For high-wear industrial environments, phosphate coatings improve lubricity and paint adhesion, minimizing friction during assembly. These treatments not only extend the service life of square nuts in special working environments, but also reduce maintenance costs in harsh working conditions.
