Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 10683 was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee
SC 1 Mechanical properties of fasteners.
Annex A of this International Standard is for information only.

INTERNATIONAL STANDARD ISO 10683:2000(E)
Fasteners — Non-electrolytically applied zinc flake coatings
1 Scope
This International Standard specifies requirements for thickness, corrosion resistance and mechanical and physical
properties of non-electrolytically applied zinc flake coatings on steel fasteners with metric threads.
It applies to both coatings with or without chromate.
Coatings according to this International Standard may also be applied to steel screws which form their own mating
threads such as wood screws, self tapping screws, self drilling screws, thread cutting screws and thread rolling
screws as well as to non-threaded steel parts such as washers and pins.
They may be similarly applied to steel fasteners with other types of thread.
Coatings according to this International Standard can be supplied with integral lubricant and/or with a subsequently
added lubricant.

3 Terms and definitions
For the purpose of this International Standard, the definitions given in ISO 2064 together with the following apply.
3.1
non-electrolytically applied zinc flake coating (with or without integral lubricant)
coating which is produced by applying to the surface of a fastener a zinc flake dispersion, possibly with the addition
of aluminium flakes, in a suitable medium which under influence of heat (curing) generates a bonding amongst
flakes and also between flakes and substrate thus forming an inorganic surface coating sufficiently electrically
conducting to ensure cathodic protection
NOTE The coating may or may not contain chromate.
4 General characteristics
It is a characteristic of this type of coating that no hydrogen which could be absorbed by the fasteners to be coated
is generated during the coating process. Therefore, by using pretreatment cleaning methods which do not generate
nascent hydrogen (for example blast cleaning), there is no risk of hydrogen embrittlement from the surface
preparation procedure.
If cleaning methods are applied which could lead to hydrogen absorption (such as acid cleaning), then for fasteners
with a hardness above 365 HV in-process control shall be conducted to ensure that the process with regard to
hydrogen embrittlement is under control. This can be done by a preloading test according to ISO 15330.
However it should be noted that a non-electrolytically applied zinc flake coating has a high permeability for
hydrogen which, during the curing process, allows effusion of hydrogen which may have been absorbed before the
coating process.
5 Dimensional requirements and testing
Coating thicknesses which can be applied on ISO metric threads in accordance with ISO 965-1, ISO 965-2 and
ISO 965-3 depend on the fundamental deviation available as given in Table 1, which itself depends on the screw
thread and the following tolerance positions:
� g, f, e for external threads;
� G for internal threads or H if required.
The coating shall not cause the zero line (basic size) to be exceeded in the case of external threads; nor shall it fall
below in the case of internal threads. This means that for an internal thread of tolerance position H, a measurable
coating thickness can only be applied to the thread if the tolerance zone is not taken up to the zero line (basic size).
