This guide provides a detailed overview of DIN 931 bolt manufacturers, covering specifications, applications, material choices, and quality considerations. Find reputable suppliers and learn how to select the right bolts for your projects. We'll explore the critical aspects to ensure you source high-quality DIN 931 bolts for your needs.
The DIN 931 standard defines hexagonal head bolts with a coarse thread. These bolts are widely used in various industries due to their strength and reliability. Key specifications include the bolt's diameter, length, thread pitch, and material grade. Understanding these specifications is crucial for selecting the appropriate bolt for a particular application. The strength of the bolt is directly related to its material grade, typically indicated by a suffix in the part number (e.g., 8.8, 10.9, 12.9). Higher numbers denote higher tensile strength.
DIN 931 bolts are manufactured from various materials, each offering distinct properties. Common materials include carbon steel, stainless steel (e.g., A2, A4), and alloy steel. The choice of material depends on the application's environmental conditions and required strength. For example, stainless steel bolts are preferred in corrosive environments, while high-strength alloy steels are suitable for applications requiring exceptional load-bearing capacity.
| Material | Strength | Corrosion Resistance | Applications |
|---|---|---|---|
| Carbon Steel | High | Low | General purpose |
| Stainless Steel (A2) | Medium | Good | Outdoor, corrosive environments |
| Stainless Steel (A4) | High | Excellent | Highly corrosive environments |
| Alloy Steel | Very High | Medium | High-strength applications |
