Key dimensions
EN 14399-4 HV bolt head dimensions.
HV heads are larger across flats than ISO 4014 bolts so a bigger bearing face carries the preload. Bolt, nut and washers must come from one EN 14399 set. Nominal values cross-checked against the published sources below; the governing standard edition and your drawing control the order.
