FAQs
DIN931 bolts are half-buckle hexagonal bolts. It complies with the standards set by the Deutsches Institut für Normung (DIN), the German Institute for Standardization.
DIN931 bolts are typically made from materials such as steel, stainless steel or other alloys, depending on application requirements. Commonly used materials for DIN931 bolts include:
1. DIN931 bolts made of carbon steel: Suitable for general applications, carbon steel bolts have good strength and hardness.
2. DIN931 bolts made of stainless steel: Stainless steel bolts are known for their corrosion resistance and are very suitable for environments that require rust prevention.
3. DIN931 bolts made of alloy steel: Alloy steel bolts have higher strength and wear resistance and are preferred for applications requiring extra strength and durability.
4. Plastic material DIN931 bolts: It is often used in food machinery and other fields.
In addition, there are hexagonal bolts made of copper and aluminum. DIN931 bolts are available in a variety of different materials to suit a variety of applications.
