This standard consequently replaces the old national standard, DIN 267 Teil 9. This standard is identical to the international standard ISO 4042 (1st. For electroplating of fasteners, the requirements of this document apply, unless otherwise agreed. DIN : 267 Part 9 ISO : 4042 ANSI : In June 1992 a new national German standard, DIN ISO 4042-electrolytic surface plating, was published. NOTE Other International Standards specify differing electroplating processes. This document does not specify requirements for properties such as weldability or paintability. Information for design and assembly of coated fasteners is given in Annex A. This document applies to bolts, screws, studs and nuts with ISO metric thread, to fasteners with non-ISO metric thread, and to non-threaded fasteners such as washers, pins, clips and rivets. DIN EN ISO 4042 A 1) Kennbuchstabe für Überzugsmaterial A Zink (Zn) 2 2) Kennzahl für Schichtdicke in µm 2 5 µm F 3) Kennbuchstabe für den Glanzgrad und die Nachbehandlung (Chromatierung) F blank, Farbe bläulich. Specifications for other electroplated coatings and coating systems (tin, tin-zinc, copper-tin, copper-silver, copper, silver, copper-zinc, nickel, nickel-chromium, copper-nickel, copper-nickel-chromium) are included in this document only for dimensional requirements related to fasteners with ISO metric threads. HS CodeProduct DescriptionOriginDestin. with or without lubricant (integral lubricant and/or subsequently added lubricant). This document does not specify requirements for properties such as weldability. The following tables are in accordance with the contents of ISO 4042. It mainly applies to zinc and zinc alloy coating systems (zinc, zinc-nickel, zinc-iron) and cadmium, primarily intended for corrosion protection and other functional properties: Fuller Fasteners, Distributor of Metric and Imperial Fasteners, stainless steel, brass, nylon, hex nuts, bolts, nuts, screws, taps, dies, tools and kn95. This document applies to bolts, screws, studs and nuts with ISO metric thread, to fasteners with non-ISO metric thread, and to non-threaded fasteners such as washers, pins, clips and rivets. It also specifies requirements and gives recommendations to minimize the risk of hydrogen embrittlement see 4.4 and Annex B. The requirements related to dimensional properties also apply to fasteners made of copper or copper alloys. This document specifies requirements for electroplated coatings and coating systems on steel fasteners.
