The HV nuts are lubricated for installation. Correct installation is achieved by screwing on the HV nut EN 14399-4 with the corresponding HV bolt EN 14399-4 and HV washers EN 14399-6. Pairing of the same make ensures the correct matching and the intended tightening behaviour. Additional lubrication of bolts, nuts and washers changes the preload parameters and causes assembly errors.

Transportation and storage
