Ordering code for electroplated coatings for commercial fastenersĮxample of coding: A3L means zinc-plating (A in Table 1) with a minimum layer thickness of 8 µm In the case of other electroplated coatings, "P" in the code symbol signifies "degree of gloss optional". Yellowish glistening to yellowish-brown,iridescentī, C or D (3) at manufacturer’s discretionġ) Passivation treatments are possible only with zinc or cadmium coatings.Ģ) However, process group A Only applies to Zn coatingsģ) Process groups B, C or D in accordance with DIN 50 941 only apply to cadmium and zinc coatings. Layer thickness (coating structure) in µmġ) Code number 0 applies to screw threads below M 1.6, where no specific layer thickness can be specified.Ģ) Does not apply to threaded components. Minimum layer thickness (coating structure) This callout system is built up as follows: – a capital letter for the coating metal (Table 1) – a number for the minimum layer thickness (coating structure) (Table 2) – a capital letter for the degree of gloss and after-treatment (Table 3) The electroplated coatings of mechanical fasteners are designated by a code consisting of a combination of two capital letters and a number. This information on electroplated coatings corresponds with DIN 267 Part 9 and ISO 4042. Note: The use of the nomenclature “galvanizing” for this treatment is not correct. These technical conditions are in particular related to threaded fasteners (mainly bolts and nuts), but are also applicable to the whole range of mechanical fasteners.Īn electrolytically applied coating shall be defined as a protective metallic layer being deposited onto the surface of metal articles by immersing these parts in an aqueous solution through which an electrical current is passed.
