It is the requirement that the manufacturer of the EN 14399 assembly will supply them suitably lubricated. The lubrication can be applied either on the bolt thread (external) or the nut thread (internal). Andrews Fasteners, in a majority of cases, choose to apply lubrication on the internal thread of the nuts. Due to the method used to lubricate the nuts, typically they need to be immersed in lubricant in full. Depending on the type of process used, the appearance of the nuts can differ, especially on Hot Dip Galvanised (HDG) nuts.
