This British Standard specifies the coatings, dimensions, materials, lubrication and performance requirements for prevailing torque type bolts, screws and studs, with non-metallic prevailing torque elements incorporated into the thread, when tested at an ambient room temperature between 15 °C and 30 °C.
It applies to bolts, screws and studs:
The torque/clamping force requirements do not apply to set screws and similar threaded fasteners with physical properties in conformance with BS 6104-3:1981.
NOTE 1 Capability to provide a pressure or liquid seal is not within the requirements of this standard.
NOTE 2 Performance at temperatures outside the operating range is not within the requirements of this standard.
NOTE 3 Performance of bolts, screws and studs for which a lubricated coating is not permissible is not within the requirements of this standard.
