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. 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. 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. with or without lubricant (integral lubricant and/or subsequently added lubricant). for the coating metal (Table 1) a number for the minimum layer thickness (coating. Zinc Plating is deposited on the surface of the component. Information for Designers Thickness and Growth. Please contact us with your requirements. The requirements related to dimensional properties. ISO 2081 (replaces BS 1706 and BS EN 12329) ASTM B633 Def Stan 03-20 (replaces DTD 903D) MIL-STD-171 1.9.1, 1.9.2 We can work to many other specifications, but the above are our most popular. 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: ISO : 4042 (EN ISO 4042) DIN : 267 Part 9 Electroplated Coatings. This document specifies requirements for electroplated coatings and coating systems on steel fasteners. It also specifies requirements and gives recommendations to minimize the risk of hydrogen embrittlement see 4.4 and Annex B.

Nomenclature - examples SVF std 2000, Revision 2 ISO 20 5 micron zinc on steel, blue chromated : Fe/Zn5/C1: Fe/Zn5/A : A2B: 8 microns of zinc on steel, yellow chromated: Fe/Zn8/C2: Fe/Zn8/C : A3c: 12 microns zinc to steel, green chromating: Fe/Zn12/C3: Fe/Zn12/D : A4D: 15 microns zinc on. The requirements related to dimensional properties also apply to fasteners made of copper or copper alloys. According to ISO 4042/2081 DIN 267/9: A2 L According to SS: 3191/2968 Fe/Zn 5 c. This document specifies requirements for electroplated coatings and coating systems on steel fasteners.
