The DIN 1587 dome nut, made from A4 (Grade 316) "marine-grade" stainless steel, is a closed, rounded hex nut prized for its superior corrosion resistance and finished appearance. Its primary purpose is to provide a safe, aesthetically pleasing cover for exposed bolt ends in harsh environments, such as marine or chemical processing applications.
