BS EN ISO 898-1:2009 Mechanical properties of fasteners made of carbon steel and alloy steel. Bolts, screws and studs with specified property classes. Coarse thread and fine pitch thread

BS EN ISO 898-1 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. They might not retain the specified mechanical and physical properties at higher or lower temperatures.

BS EN ISO 898-1 applies to bolts, screws and studs:

a) Made of carbon steel or alloy steel
b) Having triangular ISO metric screw thread according to ISO 68-1
c) With coarse pitch thread M1,6 to M39, and fine pitch thread M8×1 to M39×3
d) With diameter/pitch combinations according to ISO 261 and ISO 262
e) Having thread tolerances according to ISO 965-1, ISO 965-2 and ISO 965-4

It does not apply to set screws and similar threaded fasteners not under tensile stresses (see ISO 898-5).

It does not specify requirements for such properties as:

  • Weldability
  • Corrosion resistance
  • Resistance to shear stress
  • Torque/clamp force performance
  • Fatigue resistance.
