DIN 912
DIN 912 is a standard from the German Institute for Standardization (DIN) for cylindrical screws with an internal hexagon socket. This standard defines the dimensions, tolerances, and mechanical properties of cylindrical screws used for a wide range of mechanical and structural applications. Cylindrical screws according to DIN 912 are available in various sizes and materials to meet different requirements.
Features and Dimensions
DIN 912 cylindrical screws come in various diameters and lengths, with common thread sizes ranging from M1.6 to M48. These screws have a cylindrical head and an internal hexagon drive, which allows secure assembly and disassembly with a hex key. The standardized dimensions ensure a reliable and consistent fit.
Materials and Surface Treatments
DIN 912 cylindrical screws are made from various materials to meet different requirements for strength, corrosion resistance, and temperature resistance. Common materials include:
-
Steel (Grades 8.8, 10.9, 12.9)
-
Stainless steel (A2, A4)
-
Brass
Additionally, screws can have various surface treatments to enhance corrosion resistance. Frequently used surface treatments include:
-
Zinc plating
-
Blackening
-
Nickel plating
Applications
DIN 912 cylindrical screws are used in many fields, including:
-
Mechanical engineering: For fastening components and constructions in machines and systems.
-
Automotive industry: To secure bolted connections in vehicles.
-
Construction industry: To secure structural connections in buildings and bridges.
-
Electrical engineering: For fastening electrical components and enclosures.
Assembly and Use
When assembling DIN 912 cylindrical screws, it is important to select the correct size and suitable material to ensure optimal performance and longevity of the connection. The internal hexagon drive enables easy and secure assembly with an appropriate hex key or machine.
Conclusion
DIN 912 cylindrical screws are essential fastening elements in many mechanical and structural applications. Their standardized dimensions and materials guarantee a reliable and secure connection that meets the demands of various uses.
