Overview
SIST EN 2867:2010 defines the requirements for aerospace self-locking, floating anchor nuts with a single lug and counterbore, manufactured from heat resisting steel and lubricated with molybdenum disulphide (MoS₂). This European Standard supports high-performance fastening in aerospace assemblies, offering a classification of 1100 MPa tensile strength at ambient temperature and 315 °C maximum temperature resistance. Adopting these specifications ensures reliability, safety, and compatibility for demanding environments within the aerospace sector.
Key Topics
- Anchor Nuts Construction: Floating, single-lug design for use in locations where slight misalignment may occur, allowing easier assembly in restricted spaces.
- Self-Locking Mechanism: Achieved by forming the upper portion out-of-round to prevent loosening under vibration or thermal cycling, vital for flight safety.
- Material Choice: Fabricated from heat resisting steels compliant with referenced EN and ISO standards, ensuring strength retention at elevated temperatures.
- Lubrication: MoS₂ (molybdenum disulphide) dry lubricant coating minimizes galling and friction, enhancing installation and longevity.
- Dimension and Tolerance Compliance: Designed in line with ISO 3224 and ISO 5855-2 specifications for MJ threads and dimensional control.
- Marking & Traceability: Marked according to EN 2424, supporting clear identification and traceability throughout the aerospace supply chain.
Applications
- Aircraft Structural Assembly: Used extensively in aircraft fuselage, wing, and section joins where load requirements reach up to 1100 MPa and high thermal resistance is needed.
- Engine and Powerplant Attachments: Suitable for fastening components exposed to elevated temperatures (up to 315 °C) without degradation of mechanical or locking properties.
- Maintenance and Repair: The floating anchor nut design enables simplified service or replacement of components in constrained or blind locations.
- Spacecraft and Defense Systems: Preferred in high-reliability assemblies where performance, vibration resistance, and non-loosening are critical.
