SIST EN ISO 3506-6:2022

This document specifies general rules and provides technical information on stainless steels and their properties, which are relevant when using other parts of the ISO 3506 series. It includes specifications for corrosion-resistant stainless steels and nickel alloys, which are suitable for the manufacture of fasteners.
It applies to austenitic, martensitic, ferritic and duplex (austenitic-ferritic) stainless steel grades and nickel alloys for fasteners, and is intended to be used together with the relevant parts of the ISO 3506 series.
Common designations of stainless steels and nickel alloys used for fasteners are given in Annex A.

Fasteners - Electroplated coating systems (ISO 4042:2022)
SIST EN ISO 4042:2022

This document specifies requirements for steel fasteners with electroplated coatings and coating systems. The requirements related to dimensional properties also apply to fasteners made of copper or copper alloys.
It also specifies requirements and gives recommendations to minimize the risk of hydrogen embrittlement, see 4.4 and Annex B.
It mainly applies to fasteners with zinc and zinc alloy coating systems (zinc, zinc-nickel, zinc-iron) and cadmium, primarily intended for corrosion protection and other functional properties:
—    with or without conversion coating,
—    with or without sealant,
—    with or without top coat,
—    with or without lubricant (integral lubricant and/or subsequently added lubricant).
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.
The requirements of this document for electroplated fasteners take precedence over other documents  dealing with electroplating.
This document applies to steel bolts, screws, studs and nuts with ISO metric thread, to other threaded fasteners and to non-threaded fasteners such as washers, pins, clips and rivets.
NOTE       Electroplating is also applied to stainless steel fasteners, e.g. for the purpose of lubrication in order to avoid galling.
Information for design and assembly of coated fasteners is given in Annex A.
This document does not specify requirements for properties such as weldability or paintability.

Fasteners - Acceptance inspection (ISO 3269:2019)
SIST EN ISO 3269:2019

This document specifies an inspection procedure to be used by the purchaser where no prior agreement exists.
It also specifies a reference acceptance procedure for acceptance or rejection of an inspection lot, when no agreement can be reached between the purchaser and the supplier, or where conformance to specification is disputed.
It applies to inspection lots of bolts, screws, studs, nuts, pins, washers, rivets and other related fasteners.
This document applies to fasteners not intended for high volume machine assembly, special-purpose applications or specially engineered applications requiring more advanced in-process control and lot traceability.
For in-process control or final inspection by the manufacture and sorting, see ISO 16426.

—          with or without hexavalent chromium;
—          with or without top coat;
—          with or without lubricant (integral lubricant and/or subsequently added lubricant).
It is applicable 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, etc.
This document does not specify requirements for such fastener properties as weldability or paintability. It is not applicable to mechanically applied zinc coatings.
NOTE       Coatings in accordance with this document are especially used for high strength fasteners (≥ 1 000 MPa) to avoid risk of internal hydrogen embrittlement (IHE — see 4.4).
Information for design and assembly of coated fasteners is given in Annex A.

This European Standard specifies together with EN 14399-1 and EN 14399-2, the requirements for assemblies of high-strength structural bolts and nuts of system HV suitable for preloaded joints with large widths across flats, thread sizes M12 to M36 and property classes 10.9/10.
Bolting assemblies (including fit bolts with nominal shank diameter d + 1 mm) in accordance with this document have been designed to allow preloading of at least 0,7 fub × As ) according to EN 1993-1-8 (Eurocode 3) and to obtain ductility predominantly by plastic deformation of the engaged threads. For this purpose the components have the following characteristics:
-   nut height approximately 0,8 d;
-   bolt with short thread length.
Bolting assemblies in accordance with this document include washers according to EN 14399-6.
NOTE   Attention is drawn to the importance of ensuring that the bolting assemblies are correctly used if satisfactory results are to be obtained. For recommendations concerning proper application, reference to EN 1090-2 is made.
