EN 2867:2009 - Aerospace series - Nuts, anchor, self-locking, floating, one lug, with counterbore, in heat resisting steel, MoS2 lubricated - Classification: 1 100 MPa (at ambient temperature) / 315 °C

Overview

EN 2867:2009 specifies the characteristics of one-lug, floating anchor nuts with a counterbore and an integral self-locking feature achieved by forming the upper portion out-of-round. The nuts are manufactured from heat-resisting steel and are MoS2 (molybdenum disulphide) lubricated. Classification is 1 100 MPa (ambient) / 315 °C (maximum service temperature). This standard is intended for aerospace applications where reliable locking and elevated temperature performance are required.

Key Topics

  • Scope and configuration: Defines one-lug floating anchor nuts with counterbore and the self-locking zone formed by out-of-round deformation. Dimensional requirements are aligned with ISO 3224.
  • Materials: Acceptable heat-resisting steels are referenced (see EN 2398, EN 2399, EN 3638, EN 3639 and related technical reports). Material selection supports the 1 100 MPa strength classification.
  • Surface treatment and lubrication: MoS2 dry lubricant per EN 2491 is specified; surface texture and edge break criteria are given to support consistent coating and performance.
  • Marking and designation: Marking follows EN 2424; designation format and optional purchaser options (e.g., countersunk or dimpled rivet holes) are described.
  • Quality and approval: Manufacturer approval and quality-system expectations reference EN 9100 and qualification of nuts is aligned with EN 9133.

Applications

EN 2867:2009 nuts are intended for aerospace fastenings that require:

  • Secure self-locking engagement under vibration and service loads.
  • Floating (radial float) capability to aid alignment during assembly of structural components.
  • High-temperature resistance up to 315 °C without permanent degradation when returned to ambient conditions.
  • Compatibility with high-strength bolts of equivalent strength class (1100 MPa) for load-sharing and joint integrity.

Typical use cases include airframe assemblies, engine-related fastenings where elevated temperatures occur, and other critical aerospace joints requiring removable but vibration-resistant fasteners.

Related Standards

EN 2867 references several normative documents that practitioners should consult for full specification and procurement:

  • EN 2398, EN 2399, EN 3638, EN 3639 (heat-resisting steels and fastener materials)
  • EN 2491 (MoS2 dry lubricants - coating methods)
  • EN 2424 (marking of aerospace products)
  • ISO 3224 (dimensions for one-lug floating anchor nuts)
  • ISO 5855-2, ISO 5858, ISO 8788 (thread and tolerance standards)
  • EN 9100 and EN 9133 (quality management and qualification for aerospace standard parts)

For manufacturers, designers and procurement specialists, EN 2867:2009 provides a concise specification to ensure consistent production, traceability and performance of anchor, self-locking floating nuts used in demanding aerospace environments.
