The HV nuts are lubricated for installation. Correct installation is achieved by screwing on the HV nut EN14399-4 with the corresponding HV bolt EN14399-4 and HV washers EN14399-6. 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.
Heavy hex bolting assemblies are designed for high strength structural joints and are subject to specific regulations. Bolts are to be used with nuts EN 14399-4 and washers 14399-6.
Individual replacement of parts is not recommended.
