DIN981/GB912/GB810 M65 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.

Stainless steel DIN981/GB912/GB810 M65 round nut is a key fastener used for connecting and locking shaft parts in industrial equipment. It is made of austenitic stainless steel SS304. This stainless steel contains about 18-20% chromium and 8-10% nickel, and has excellent corrosion resistance, good heat resistance and high machinability. Thanks to these material properties, M65 round nuts can maintain stable performance in a variety of complex or harsh environments, especially suitable for use in humid, chemical media or high cleaning requirements.

The M65 specification means that its thread nominal diameter is 65 mm, and it adopts a coarse thread structure, which makes it have stronger torque bearing capacity and vibration resistance in heavy-duty connections. Under high-intensity and high-frequency installation and disassembly conditions, this type of nut can effectively maintain fastening stability and reduce the risk of loosening. The appearance of the nut is the natural color of stainless steel, without additional surface treatment, showing the true state of its original material, which is both simple and practical, and has long-term weather resistance.

This product complies with the requirements of multiple standards such as DIN981, GB912, GB810, etc., and is strictly controlled within the standard tolerance range from structural dimensions to mechanical properties. Its rated strength is 700PA, which is suitable for fastening parts of large and medium-sized equipment, such as large bearing assembly, flange end face fixing, wind turbine structure connection, etc., and can withstand the impact and load brought by high-intensity working conditions.

This stainless steel round nut is not only widely used in traditional industrial fields such as machinery manufacturing, engineering equipment, and power facilities, but also plays an important role in industries with high requirements for cleanliness and corrosion resistance such as petrochemical equipment, chemical production lines, food processing equipment, medical equipment, and architectural decoration. Its excellent comprehensive performance makes it a reliable fastening solution that takes into account both mechanical strength and environmental adaptability.
