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

All standards are subject to revision, and parties to agreements based on this part of IS0 are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below.

This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. Nuts with specified proof load values — Fine pitch thread [5]. The test applies to bolts and screws with thread less than M3 for which no breaking and proof loads are indicated In IS0as well as to short bolts and screws with nominal diameters 3 mm to 10 mm which cannot be subjected to a tensile test.

For the note time being, minimum breaking torques can specified for property classes 8.

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


The standards do not cover fasteners that would otherwise apply but require special properties, such as weldability or corrosion resistance. Also since bolts and screws with threads greater than M3 LID to anproximately Ml0 often cannot be subjected to a tensile test or proof load test due to their short lengths, minimum, breaking torques have been specified for bolts and screws Ml to Ml0 ineluding the fine pitch threads M8 x 1: Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
