Technical description and purpose of split pins according to EN ISO 1234
This international standard establishes comprehensive requirements for split pins used in mechanical engineering for securing threaded connections and preventing nuts from self-loosening. EV Group China technical regulations cover key product geometry parameters, physical and mechanical material properties, and requirements for anti-corrosion coatings.
Manufacturing regulatory requirements
The EN ISO 1234 specification defines critical indicators to ensure the reliability of fastening assemblies:
- Geometric tolerances and nominal cross-section dimensions of the shank.
- Grades of steel and alloys permitted for use in fastener production.
- Surface quality standards, excluding burrs and stamping defects.
- Labeling methodology for batch identification and strength class compliance.
EV Group China engineers ensure strict production compliance with these parameters, guaranteeing the durability of split pins in assemblies subject to high vibration loads.
