Code system The The electroplated coatings of mechanical mechanical fasteners fast eners are designated designated by a code consisting consis ting of a combination combination of two capital letters and a number. This This information information on electroplated coatings correspond corres pondss with wit h DIN 267 Part 9 and ISO 4042. Note: The use of the nomenclature “galvanizing” for this treatment is not correct.
Electropl Elect roplated ated coatings coa tings An electrolytically electrolyti cally applied applied coating shall be defined defined as a protective metallic metallic layer lay er being deposited deposited onto the surface of metal articles by immersing these parts in an aqueous solution through which an electrical current is passed. Scope and field of applicati application on These These technical conditions are in particular related to threaded fasteners (mainly (mainly bolts and nuts), but are also applicable to the whole range of mechanical fasteners.
