Stud DIN444 refers to bolts conforming to the Chinese national standard GB798, which are often referred to as live bolts or ring eye bolts.The DIN444 standard specifies the type and size, technical conditions and markings of live bolts. These bolts are usually used in applications where high strength and reliability are required, such as lifting, suspension or fixed loads.

Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.

Grade: The product grade is divided into A grade and B grade, as well as different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.

Advantage:

Standardized production: conforms to national standards, ensuring quality and reliability. High strength: usually made of high-strength materials, capable of withstanding large working loads. Wide range of applications: Suitable for a wide range of industrial and mechanical applications, especially in environments where tensile strength is required. Eyelet design: the eyelet section facilitates the use of slings, chains or other types of suspension. CORROSION RESISTANCE: Depending on the material and surface treatment, it has a certain degree of corrosion resistance.

Scope of 

application

1.Lifting and hoisting: for fixing and lifting heavy loads in cranes, slings and hoisting equipment. 2. building and structural: for fixing building structures and steel frames. 3. machine building: for fixing and connecting components in mechanical equipment. 4. automotive industry: for fixing of car chassis and suspension systems. 5. Shipbuilding: for joining and fixing structural parts of ships.
