EN 2883:2009 - Aerospace series - Nuts, hexagonal, self-locking, with counterbore and captive washer, in heat resisting steel, MoS2 lubricated - Classification: 1 100 MPa (at ambient temperature) / 315 °C

Overview

EN 2883:2009 (CEN) specifies the characteristics of aerospace-series hexagonal self-locking nuts with a counterbore and captive washer, manufactured from heat-resisting steel and MoS2 (molybdenum disulphide) lubricated. The standard covers nuts classified 1 100 MPa (minimum tensile stress at ambient temperature) and rated for service up to 315 °C (maximum temperature without continuous change, as determined by surface treatment).

Key topics and requirements

  • Scope and configuration: Defines nut geometry (hexagonal body, counterbore, captive washer) and general arrangement; dimensions and tolerances reference ISO 8538 (detailed sizes are given in the standard’s tables).
  • Mechanical classification: Classification 1 100 MPa / 315 °C - 1100 MPa indicates the nut’s minimum tensile stress resistance at ambient temperature; 315 °C is the max temperature after which original characteristics must be retained on return to ambient.
  • Materials and treatments:
    • Base material: heat-resisting steel (materials guidance referenced in TR 3791).
    • Lubrication: MoS2 coating in accordance with EN 2491.
    • Washer treatment: passivation/decontamination per EN 2516 (process class appropriate to material).
  • Dimensional and form tolerances: Form/position tolerances per ISO 8788; dimensions as per ISO 8538 and applicable nuts table.
  • Marking and designation: Marking style per EN 2424; example designation format shown (e.g., EN2883-050).
  • Quality and approval: Manufacturer approval and quality system requirements reference EN 9100 and part-qualification guidance EN 9133; procurement/inspection aligns with ISO 5858 (with noted exceptions).

Applications and users

  • Typical use: high-temperature, high-strength aerospace assemblies, such as engine components, hot-structure fastenings, and other critical bolted joints where self-locking retention and temperature resistance are required.
  • Primary users:
    • Aerospace OEMs and Tier suppliers specifying fasteners for airframe and engine assemblies
    • Fastener manufacturers producing MoS2-lubricated, heat-resisting nuts
    • Procurement and specification engineers selecting standardized parts
    • Quality, inspection and certification teams applying EN 9100/EN 9133 product qualification
    • Maintenance and repair organizations requiring standard replacements

Related standards

  • EN 2491 - MoS2 dry lubricants (coating)
  • EN 2516 - Passivation / decontamination of washer materials
  • ISO 8538 - Dimensions for similar nuts
  • ISO 5855-2 / ISO 5858 - Thread and procurement specifications
  • ISO 8788 - Tolerances of form and position
  • TR 3791 - Materials for self-locking nuts
  • EN 2424, EN 9100, EN 9133

EN 2883:2009 enables consistent specification, procurement and manufacture of MoS2-lubricated, heat-resistant, self-locking hex nuts for aerospace applications where high strength and elevated temperature performance are required.
