Request QuoteMonel bolts are the alloys of nickel and copper, like Monel 400 and Monel K500. They offer superior resistance to corrosion in aquatic systems, acidic environments and high temperatures, which makes them well suited to marine equipment, offshore platforms, chemical processing systems, and oil and gas industries where the standard steel bolts do not perform. These bolts are of high tensile strength, great mechanical stability and high service life with a natural silver-grey look. Monel bolts can be of different types, i.e., hex bolts, stud bolts or socket head bolts, and are produced in conformity to international standards, e.g., ASTM F467, to ensure good performance even in harsh and highly corrosive operating environments.
