Notes on use
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.
Nuts are to be used with bolts EN 14399-4 and washers EN 14399-6.
Heavy hex bolting assemblies are designed for highstrength structural joints and are subject to specific regulations. Individual replacements of parts is not recommended.
