Mechanische Eigenschaften von Verbindungselementen. Nuts with specilied proof load values – Coarse ieo Part 5: Customers who bought this product also bought BS EN Nuts with specified proof load values — Coarse thread [3].

Nuts with specified proof load values — Coarse thread [3] 5. Nuts with specified proof load values — Fine pitch thread [5].

The test applies to ieo 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.

Worldwide Standards We can source any standard from anywhere in the world.

Set screws iiso similar threaded fasteners not under tensile stresses Part 6: 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 isi 1: It defines properties for sizes M1.

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.

Torsional test and minimum torques for bolts and screws with nominal diameters 1 mm to,10 mm 1 scope 3. The properties are defined for M1. Bolts, screws and studs with specified property classes — Coarse thread and fine pitch thread [2].

Bolts, screws and studs Part 2: 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. 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.

Clamp the bolt or screw into the test device over at least two full threads, having a free thread length of at least one thread diameter present between the head of the bolt or screw and the threaded insert see figure Iao.

Torsional test and minimum torques for bolts and screws with nominal diameters 1 mm to 10 mm. Mechanical properties of fasteners. Part 6 is the same as part 2 except for fine threaded nuts that range from M8 to M The work of preparing International Standards is normally carried out through IS0 technical committees.
