DIN981/GB912/GB810 M85 Round Nuts

Made from Austenitic stainless steel, they contain about 18-20% chromium and 8-10% nickel, offering exceptional corrosion resistance and good machinability.In the chemical, petrochemical, and food processing industries, SS304 nuts are favored due to their corrosion resistance and hygiene properties. They are also widely used in medical devices, architectural decorations, and machinery.

The Stainless Steel DIN981/GB912/GB810 M85 Round Nut is an industrial fastener made from high-quality 304 stainless steel. This material offers excellent corrosion resistance and mechanical properties, effectively resisting oxidation, acids, alkalis, and other corrosive media, making it suitable for humid, chemical, and high-temperature environments.

With a nominal thread diameter of 85 mm (M85), this large-sized round nut is commonly used in mechanical manufacturing, steel structures, shipbuilding, bridges, and pipeline systems, where it plays a critical role in secure fastening.

The nut features coarse threads (COARSE THREAD), which provide superior anti-vibration and anti-loosening performance compared to fine threads, ensuring stability in high-vibration applications and enhancing operational safety. The threads are unmarked (NO MARK), complying with DIN standard requirements for uniformity and ease of installation.

The nut retains the natural color of stainless steel without additional coatings, leveraging 304 stainless steel’s inherent corrosion resistance to reduce maintenance costs and extend service life. Its well-engineered structure and high-precision manufacturing ensure smooth thread engagement and easy installation/removal, making it widely applicable in industrial manufacturing, heavy machinery, petrochemical, and construction engineering.

Thanks to its premium material selection, strict standard compliance, and reliable mechanical performance, the Stainless Steel DIN981/GB912/GB810 M85 Round Nut serves as a crucial component in large-scale equipment and structural connections, meeting demanding environmental and high-strength requirements while ensuring operational safety and construction quality.
