DIN 915
DIN 915 is a standard from the German Institute for Standardization (DIN) for threaded pins with internal hexagon and shoulder. This standard defines the dimensions, tolerances, and mechanical properties of threaded pins used to secure components in bores or on shafts. Threaded pins according to DIN 915 are available in various sizes and materials to meet different requirements.
Features and Dimensions
DIN 915 threaded pins come in various diameters and lengths, with common thread sizes ranging from M3 to M24. These pins have a shoulder that grips into the material, providing secure fixation. The internal hexagon drive allows easy assembly and disassembly with a hex key.
Materials and Surface Treatments
DIN 915 threaded pins are made from various materials to meet requirements for strength, corrosion resistance, and temperature resistance. Common materials include:
Brass
Additionally, the pins may have surface treatments such as zinc plating, blackening, or passivation to enhance corrosion resistance.
Applications
DIN 915 threaded pins are used in many fields, including:
Mechanical engineering: For securing gears, pulleys, and other components on shafts.
Electrical engineering: For securing electrical components and housings.
Furniture industry: For assembling furniture parts where a concealed connection is required.
Automotive industry: For securing components in engines and chassis.
Assembly and Use
When assembling DIN 915 threaded pins, it is important to choose the correct size and appropriate material to ensure optimal performance and durability of the connection. The internal hexagon drive enables easy and secure assembly with a suitable hex key or machine.
Conclusion
DIN 915 threaded pins are essential fastening elements in many mechanical and electrical applications. Their standardized dimensions and materials ensure reliable and secure fixation that meets the demands of various applications.
