Part 1 defines the mechanical properties of bolts, screwsand studs. Also since bolts and screws with threads greater than M3 LID to anproximately Ml0 often cannot be subjected io 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. Bolts, screws and studs with specified property classes — Coarse thread and fine pitch thread .
BS EN 20898-7:1995, ISO 898-7:1992
The minimum breaking torques have been determined on the basis of cross-sections resulting from the minimum values of the minor diameter of the thread tolerance 6g.
It also excludes set screwswhich are covered under part 5. The properties are defined for M1. Torsional test and minimum torques for bolts and screws with nominal diameters 1 mm to 10 mm. Set screws and similar threaded fasteners not under tensile stresses . Nuts with specified proof load values — Coarse thread  5. All standards are subject to revision, and parties to agreements based on this part of IS0 are encouraged to investigate the possibility iwo applying the most recent edition of the standard indicated below.
Torsional test and minimum torques for bolts and screws with nominal diameters 1 mm to 10 mm Status: 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 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.
Worldwide Standards We can source any standard from anywhere in the world. 898–7 the time of publication, the edition indicated was valid. Figure 1 is only an example of a suitable test device.
Ml0 x 1 and Ml0 x 1,25 which allow an evaluation of the functional properties of the bolts and screws. Accept and continue Learn more about the cookies we use and how to change your settings. Part 6 is the same as part 2 except for fine threaded nuts that range from M8 to M Take the smart route to manage is device compliance.
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.

Mechanische Eigenschaften von Verbindungselementen. Bolts, screws and studs Part 2: Tests have shown that the torques can also be used for bolts and screws with thread tolerances 6f and 6e. Torsional test and minimum torques for bolts and screws with nominal diameters 1 mm to,10 mm 1 scope 3.
The work of preparing Io Standards is normally carried out through IS0 technical committees. Find Similar Items This product falls into the following categories. 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.
