ISO is an international standard that defines mechanical and physical properties for metric fasteners. Bolts, don and studs with specified property classes — Coarse thread and fine pitch thread [2]. Nuts with specified proof load values — Coarse thread [3].

Set screws and similar threaded fasteners not under tensile stresses [4]. Nuts with specified proof load values — Fine pitch thread [5]. With exception to part 7, which defines test standards, the parts of this standard define properties for fasteners made of carbon steel and alloy steel.

The standards do not cover fasteners that would otherwise apply but require special properties, such as weldability or corrosion resistance. Part 1 defines the mechanical properties of bolts, screwsand studs.

The properties are defined for M1. Part 1 does not specify properties for fasteners that have head geometries 20889 reduce the shear strength of the fastener, such as low head screws and countersunk heads.

It also excludes set screwswhich are covered under part 5.

Part 2 defines the mechanical properties for coarse threaded nuts up to an M39 size and a height of at least half the nominal diameter.

Part 5 defines the mechanical properties for set screws and other fasteners not under tensile stresses.

It defines properties for sizes M1. Part 6 is the same as part 2 except for fine threaded nuts that range from M8 to M From Wikipedia, the free encyclopedia.
