ISO/CD 10684

Fasteners — Hot dip galvanized coatings

Scope

ISO 10684:2004 specifies material, process, dimensional and some performance requirements for hot dip spun galvanized coatings applied to coarse threaded steel fasteners from M8 up to and including M64 and for property classes up to and including 10.9 for bolts, screws and studs and 12 for nuts. It is not recommended to hot dip galvanize threaded fasteners in diameters smaller than M8 and/or with pitches below 1,25 mm.
ISO 10684:2004 primarily concerns the spun hot dip galvanizing of threaded steel fasteners, but it may also be applied to other threaded steel parts. The specifications given in this document may also be applied to non-threaded steel parts such as washers.
