The process of hot-dip galvanizing results in a metallurgical bond between zinc and steel, with a series of distinct iron-zinc alloys. The resulting coated steel can be used in much the same way as uncoated. A typical hot-dip galvanizing line operates as follows: [2] Steel is cleaned using a caustic solution. This removes oil/grease, dirt, and ...
Galvanized surface with visible spangle. Galvanization (also spelled galvanisation) [1] is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten zinc. [citation needed]

ISO 965-2 Limits of sizes for general purpose external and internal screw threads – Medium quality ISO 965-3 Deviations for constructional screw threads ISO 965-4 Limits of sizes for hot-dip galvanized external screw threads to mate with internal screw threads tapped with tolerance position H or G after galvanizing
According to the International Zinc Association, more than 5 million tons are used yearly for both hot dip galvanizing and electroplating. [1] The plating of zinc was developed at the beginning of the 20th century. At that time, the electrolyte was cyanide based.
When coating metric threaded parts it is necessary to keep to the tolerances defined in ISO 965 so that the bolt's thread does not get gummed up and the coefficient of friction can be set accordingly. Hot-dip galvanised fasteners with a typical coating thickness of 80-200 μm have to be grooved again retrospectively in order to expose the thread.
