ISO 898-1:2013 specifies mechanical and physical properties of bolts, screws and studs made of carbon steel and alloy steel when tested at an ambient temperature range of 10 °C to 35 °C. Fasteners (the term used when bolts, screws and studs are considered all together) that conform to the requirements of ISO 898-1:2013 are evaluated at that ambient temperature range. They might not retain the specified mechanical and physical properties at elevated temperatures (see Annex B) and/or lower temperatures.
Certain bolts and screws might not fulfil the tensile or torsional requirements of ISO 898-1:2013 because the geometry of their heads reduces the shear area in the head compared to the stress area in the thread. These include bolts and screws having a low or countersunk head.
ISO 898-1:2013 is applicable to bolts, screws and studs
It is not applicable to set screws and similar threaded fasteners not under tensile stress (see ISO 898-5).
It does not specify requirements for such properties as weldability, corrosion resistance resistance to shear stress, torque/clamp force performance (for test method, see ISO 16047), or fatigue resistance.
