DIN 985: A Comprehensive Guide to This StandardThis article provides a comprehensive overview of DIN 985, a common standard for hex head bolts. It covers key specifications, applications, materials, and considerations for selection and use. Learn about the differences between DIN 985 and similar standards, and where you might find high-quality DIN 985 fasteners.
DIN 985 refers to a German standard (Deutsche Industrie Norm) specifying the dimensions and properties of hex head bolts. These bolts are widely used in various industries due to their strength, reliability, and ease of use. Understanding the intricacies of the DIN 985 standard is crucial for engineers, manufacturers, and anyone working with mechanical fasteners.
The DIN 985 standard precisely defines the dimensions of the bolt head, shank, and thread. These dimensions, including the head diameter, head height, shank diameter, and thread pitch, are crucial for ensuring proper fit and function. Tolerances are also specified to maintain consistent quality and interchangeability. Detailed dimensional tables can be found in the official DIN 985 document. You can find reputable suppliers of DIN 985 fasteners online, ensuring you source high-quality products that meet the standard's specifications.
DIN 985 bolts are manufactured from various materials, each with specific strength and corrosion resistance properties. Common materials include carbon steel, stainless steel (e.g., A2 and A4), and other alloy steels. The material grade is often indicated by markings on the bolt head. Selecting the appropriate material is essential for the intended application, considering factors like environmental conditions and required strength.
DIN 985 bolts typically utilize metric ISO threads, ensuring compatibility with other metric fasteners. The thread type and pitch are specified in the standard to guarantee proper engagement and load-bearing capacity. Precise thread dimensions are vital to prevent stripping or damage during installation.
The versatility of DIN 985 bolts makes them suitable for a broad range of applications across numerous industries. They are commonly used in:
While DIN 985 is a widely recognized standard, other standards exist for similar hex head bolts. Understanding the differences is important to ensure compatibility and proper selection. For example, ISO 4017 is an international standard for hex head bolts that shares similarities with DIN 985 but may have slight dimensional variations.
Choosing the correct DIN 985 bolt requires careful consideration of several factors, including the required strength, material compatibility, environmental conditions, and application-specific requirements. Consulting the official DIN 985 standard and seeking advice from experienced engineers or suppliers is recommended.
For high-quality DIN 985 fasteners and other industrial fastening solutions, consider exploring reputable suppliers. One such supplier, specializing in providing a wide selection of high-quality fasteners and hardware, is Hebei Dewell Metal Products Co., LTD. They offer competitive pricing and reliable service.
