Find the right DIN 933 bolt manufacturers for your needs. This guide explores the specifications, applications, and key considerations when sourcing these high-strength bolts. We'll cover material choices, quality standards, and factors to ensure you select the ideal supplier for your project. Learn how to identify reputable manufacturers and navigate the complexities of choosing the perfect DIN 933 bolt.
The DIN 933 standard specifies the dimensions and properties of hexagonal head bolts with a fine-pitch thread. These bolts are known for their high tensile strength and are frequently used in applications requiring significant load-bearing capacity. Key characteristics include the precise thread pitch, head size and shape, and the overall length, all defined within the DIN 933 standard. The material is typically high-strength steel, often specified in the order. For example, a DIN 933 bolt made of 8.8 grade steel indicates its high tensile strength and yield strength.
DIN 933 bolts are available in various material grades, each offering different strength and corrosion resistance properties. Common materials include carbon steel (e.g., 8.8, 10.9 grade), stainless steel (e.g., A2-70, A4-80), and other specialized alloys. Selecting the appropriate material depends heavily on the intended application and the environmental conditions. The grade designation indicates the tensile strength and yield strength of the bolt. For instance, an 8.8 grade bolt has a minimum tensile strength of 800 MPa and a minimum yield strength of 640 MPa.
| Material Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Corrosion Resistance |
|---|---|---|---|
| 8.8 | 800 | 640 | Low - Requires surface treatment for outdoor applications |
| 10.9 | 1040 | 900 | Low - Requires surface treatment for outdoor applications |
| A2-70 (Stainless Steel) | 700 | 560 | High |
| A4-80 (Stainless Steel) | 830 | 690 | High |
