DIN981/GB912/GB810 M33 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 M33 round nuts is a standard fastener commonly used for mechanical equipment shaft end connection, with the characteristics of stable structure, reliable locking, strong corrosion resistance, etc. The product is made of stainless steel 304, suitable for a variety of working environments, especially in humid, open air or lightly corrosive conditions. It complies with the German DIN981 standard and the Chinese GB912 and GB810 national standards, and meets the installation requirements of bearing locking, shaft end component positioning, etc.

Product features:

1. Slotted circular structure: Symmetrical notches are set on the side of the nut, which can be installed or removed by tools such as hook wrenches, and the operation is simple.
2. Coarse thread design: The connection is firm and the vibration resistance is strong. It is suitable for occasions with frequent vibration or load changes.
3. Stainless steel304 stainless steel material: It has good mechanical strength and oxidation resistance, long service life and low maintenance cost.
4. Natural color surface treatment: Keep the original color of stainless steel, no coating, simple appearance, suitable for general industrial needs.

Scope of application: This product is widely used in the shaft ends of various medium and large mechanical equipment to lock bearings, fix end covers or connect rotating parts, such as machine tool spindles, motor bearing ends, pump equipment, gear boxes and fans. Through stable axial locking force, it effectively prevents parts from loosening and axial displacement, and improves the operating stability and reliability of equipment.
