DIN981/GB912/GB810 M64 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 M64 round nut is a high-strength fastener widely used in heavy equipment and industrial systems. It is mainly made of 304 stainless steel (SS304) and is precision-machined. As a representative of austenitic stainless steel, 304 stainless steel has excellent corrosion resistance, oxidation resistance and mechanical strength. It can maintain stable performance in a variety of complex environments, especially suitable for highly corrosive working environments such as humidity, high salt, weak acid and alkali.

M64 refers to a large-size round nut with a thread diameter of 64mm. The thread type is coarse thread. This thread structure makes the product easier to bite during assembly and not easy to slip. It has stronger locking force and higher fatigue resistance. It is particularly suitable for occasions with large axial loads and frequent disassembly and assembly. Since there is no thread mark (Thread Mark: NO MARK), the nut can be more flexibly used in systems with different specifications or more mating parts in actual use. The strength grade of this product is 700PA, with good compressive and tensile properties, suitable for long-term use in high-load, high-pressure working environments.

From the appearance, the M64 round nut is natural metal color (Natural Color), without electroplating or other coating treatment, while maintaining the original texture of stainless steel, it also reduces the problem of shedding or aging caused by surface treatment. The appearance structure of this type of round nut is more rounded than that of hexagonal nuts. It is usually used with stop washers, slotted shaft ends or lock rings to effectively prevent loosening and improve the safety and durability of the entire structure.

In terms of application areas, DIN981/GB912/GB810 M64 stainless steel round nuts are widely used in key connection parts of heavy machinery manufacturing, engineering construction equipment, wind power generation, petrochemical equipment, metallurgical pipelines, power transmission, shipbuilding and other industries. Especially under extreme working conditions such as high temperature, high humidity, and high corrosion, this nut can provide reliable connection guarantees, extend the service life of equipment, and reduce maintenance costs.
