Stainless Steel 304 Hex Nut A2-70 Din934

It is made of national standard 304 stainless steel (Grade A2), with 18% chromium and over 8% nickel. The surface forms a dense oxide film, which has excellent anti-oxidation and anti-rust properties. Compared to ordinary carbon steel nuts, it is less prone to rust in humid and dusty outdoor environments and has a longer service life.

The product is manufactured strictly in accordance with the German standard DIN934. The edge dimensions, thickness, and thread tolerances all comply with international standards. The thread accuracy reaches grade 6H, which fits tightly with the corresponding specification bolts. The tightening torque is stable and reliable, effectively avoiding problems such as thread slippage and loosening.

With a performance level reaching A2-70, the tensile strength is not less than 700 MPa. It possesses excellent load-bearing capacity and toughness, and can meet the high-strength fastening requirements in most industrial equipment, mechanical structures, and building installations.

The standard hexagonal shape design is compatible with open-end wrenches, star wrenches or socket wrenches, making the operation convenient and fast. Whether for manual installation or pneumatic tool operations, it can achieve efficient fastening.

The surface has been whitened, maintaining the original color and luster of stainless steel, clean and free from pollution. It is particularly suitable for industries such as food processing, medical devices, and precision instruments that have certain requirements for cleanliness.
