Technical specifications and application area of EN 24014 bolts
The EN 24014 standard (identical to DIN EN ISO 4014) establishes strict requirements for the geometric parameters and physical-mechanical characteristics of hexagon head bolts with partial threading. This fastener is widely demanded in mechanical engineering, steel structure construction, and industrial equipment manufacturing, where high precision in part mating is required.
EV Group China supplies bolts manufactured in strict accordance with current international standards. The products are characterized by high resistance to dynamic loads and vibrations, making them an optimal choice for critical assemblies, including shock-absorbing systems.
Materials and execution
Carbon steels with subsequent heat treatment, as well as austenitic stainless steel alloys providing increased corrosion resistance in aggressive environments, are used for fastener production. The choice of material is made based on operating conditions, the required strength class, and the need for oxidation protection.
