DIN981/GB912/GB810 M56 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 corrosionresistance and hygiene properties. They are also widely used in medical devices, architectural decorations, and machinery.

Stainless steel DIN981/GB912/GB810 M56 round nut is an important part used in heavy machinery connection and fastening systems, widely used in machinery manufacturing, petrochemical equipment, pressure vessels, power facilities and other engineering assembly fields. It is mainly made of SS304 material, that is, 304 type austenitic stainless steel. This material has good corrosion resistance, strength stability and processing performance, and is a commonly used type of stainless steel in the industrial field.

The thread specification of this product is M56, which belongs to the large-size coarse thread (COARSE THREAD), suitable for bearing large loads and providing a more stable connection under vibration and impact conditions. Coarse threads are often used in industrial assembly with locking devices, such as locking washers or stop pins, to improve the overall anti-loosening ability.

The surface of the nut is natural color (Natural color), without electroplating or spraying treatment, maintaining the original color of stainless steel, and has both rust prevention and practicality. The product does not have a thread mark (THREAD MARK: NO MARK), and is often used in assembly occasions with non-standard or special matching requirements.

The nut complies with international and national standards such as DIN981, GB912, GB810, etc., ensuring its dimensional accuracy, structural strength and reliability. Its strength grade is 700PA, which means it has a high load-bearing capacity and can meet the fastening requirements of large mechanical equipment or pressure components.

Compared with hexagonal nuts, the structural design of round nuts is more suitable for systems that require locking accessories such as lock rings or circlips, and is also often used in structures such as shaft ends, flange connections and bearing assemblies.
