Technical requirements for ISO 7378 fastening elements
The international standard ISO 7378 regulates the engineering parameters and geometry of technological holes intended for the installation of cotter pins and safety wires in high-load fasteners, including bolts, screws, and threaded studs. Adherence to these tolerances is critical for ensuring the vibration resistance of connections in industrial equipment.
The technical solutions offered by EV Group China meet strict reliability requirements for hardware products of accuracy classes A, B, and C. The standardization of holes ensures the correct fixation of fasteners under conditions of cyclic dynamic loads.
Key characteristics of the standard:
- Operating range of product diameters: from 4 to 53 mm.
- Field of application: mechanical engineering, aviation industry, power equipment.
- Regulatory framework: the ISO 7378 standard is fundamental for the design of assemblies with increased requirements for protection against self-loosening.
In the engineering practice of EV Group China, the ISO 7378 standard is considered the technical equivalent of the German DIN 962 standard. The use of these specifications ensures full interchangeability of components when designing critical metal structures.
