Summarise this standard

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

  • made of carbon steel or alloy steel,
  • having triangular ISO metric screw thread in accordance with ISO 68-1,
  • with coarse pitch thread M1,6 to M39, and fine pitch thread M8×1 to M39×3,
  • with diameter/pitch combinations in accordance with ISO 261 and ISO 262, and
  • having thread tolerances in accordance with ISO 965-1, ISO 965-2 and ISO 965-4.

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.

Frequently Asked Questions

ISO 898-1 specifies mechanical and physical properties for bolts, screws and studs made from carbon and alloy steel. It is an international standard published by International Organization for Standardization (ISO).

ISO 898-1 is used by designers, fastener manufacturers, purchasers and testing laboratories. It is an international standard published by International Organization for Standardization (ISO).

ISO 898-1 is International Organization for Standardization (ISO)'s standard for mechanical properties of carbon steel fasteners, while ISO 4014 covers mechanical fasteners (International). ISO 898-1 specifies mechanical and physical properties for bolts, screws and studs made from carbon and alloy steel. ISO 4014 provides requirements, guidance or test methods for hexagon-head fasteners and dimensional requirements. It supports consistent specification, design or process control, verification and documented acceptance; the exact provisions depend on the cited part and edition.

ISO 898-1 is an international standard published by International Organization for Standardization (ISO), and is applied internationally rather than in a single country.

ISO 898-1 specifies mechanical and physical properties for bolts, screws and studs made from carbon and alloy steel. In practice it is applied by designers, fastener manufacturers, purchasers and testing laboratories.
