This guide provides a thorough overview of DIN 981 hexagon head bolts, covering specifications, material choices, applications, and where to source reliable suppliers. Learn how to choose the right DIN 981 bolt for your project and ensure optimal performance and safety.
DIN 981 bolts are a standard type of hexagon head bolt defined by the German standard DIN 981. They are widely used in various industries due to their strength, reliability, and ease of use. These bolts feature a hexagon head, allowing for tightening with a wrench. The standard specifies dimensions, tolerances, and material properties, ensuring consistency and interchangeability.
Key features include a consistent hexagon head size for efficient tightening, precise dimensions for reliable assembly, and various material options to suit different applications. Specific dimensions are detailed in the DIN 981 standard itself. It’s crucial to check these specifications before purchasing to ensure compatibility with your project needs. The standard covers different sizes and lengths of DIN 981 bolts.
DIN 981 bolts are available in various materials, each offering unique properties: Stainless steel (for corrosion resistance), carbon steel (for high strength), and other alloys depending on the specific application requirements. The choice of material significantly impacts the bolt's durability and suitability for the intended environment.
DIN 981 bolts find applications across a wide range of industries, including automotive, construction, machinery manufacturing, and general engineering. Their versatility and reliability make them a staple fastener in many engineering projects.
Common uses include securing machine components, fastening structural elements in buildings, and joining parts in various mechanical assemblies. The strength and reliability of DIN 981 bolts make them suitable for high-stress applications.
Consider factors like material, size, thread pitch, and surface finish when choosing DIN 981 bolts. The correct selection is critical for ensuring a secure and reliable connection. Don't forget to check the required grade and strength class as well.
Sourcing reliable suppliers is crucial for ensuring the quality and consistency of your DIN 981 bolts. Look for suppliers with established reputations and certifications to guarantee the products meet the standard. For high-quality DIN 981 bolts, consider exploring reputable manufacturers and distributors. One such option to consider is Hebei Dewell Metal Products Co., LTD, a leading supplier of fasteners.
Ensure your chosen supplier provides certifications demonstrating compliance with the DIN 981 standard. This ensures that the purchased bolts meet the specified quality requirements and tolerances.
While both are hexagon head bolts, DIN 931 bolts have a smaller head height compared to DIN 981 bolts. This difference impacts the suitability for various applications, particularly where head clearance is a concern.
The required size is determined by the application's specific needs and the materials being fastened. Refer to engineering specifications or consult with an expert to determine the appropriate size and grade of DIN 981 bolt.
| Material | Corrosion Resistance | Tensile Strength |
|---|---|---|
| Stainless Steel | Excellent | High |
| Carbon Steel | Moderate | Very High |
