Overview
EN 3653:2010 is a European aerospace standard issued by CEN that specifies critical requirements for one lug, floating, self-aligning anchor nuts. These nuts feature a self-locking mechanism achieved by forming the upper portion out of round and are manufactured from steel with cadmium plating and MoS2 (molybdenum disulphide) lubrication. Classified for a tensile strength of 900 MPa at ambient temperature and capable of withstanding temperatures up to 235 °C, these nuts are designed for demanding aerospace applications where secure, reliable fastening and alignment are essential.
Key Topics
- Material Composition: Nuts are made from steel conforming to EN 2542 and EN 2543 standards and coated with cadmium plating per EN 2133 to resist corrosion while maintaining structural integrity.
- Self-Locking Feature: Achieved through forming the top section of the nut out of round, providing reliable locking without additional locking devices.
- Floating and Self-Aligning Design: Allows the nut to compensate for misalignments during assembly, improving joint quality and service life.
- Lubrication: MoS2 dry lubricant coating per EN 2491 enhances thread function, reduces friction, and prevents galling.
- Dimensional Specifications: Precise thread dimensions and tolerances align with ISO 5855-2 and ISO 8788, ensuring interchangeability and consistent performance.
- Surface Treatment: Continuous cadmium plating with a minimum thickness of 5 µm is applied on load-bearing contact surfaces to prevent corrosion.
- Temperature Classification: Standard ensures nuts maintain integrity and performance at temperatures up to 235 °C without permanent alteration.
Applications
EN 3653:2010 nuts are essential components in the aerospace sector for fastening assemblies subject to high strength and temperature requirements. Typical applications include:
- Aircraft structural joints where floating and self-aligning fastening is required to accommodate slight misalignments during assembly.
- High-performance aerospace systems demanding self-locking nuts to prevent loosening due to vibration or thermal expansion.
- Components operating within environments reaching up to 235 °C, maintaining mechanical properties under thermal stress.
- Aerospace manufacturing processes requiring parts with certified surface treatments and dimensional precision to assure safety and longevity.
Implementing EN 3653:2010 ensures compatibility, reliability, and adherence to rigorous aerospace quality management standards like EN 9100 and EN 9133.

To fully meet aerospace industry requirements, EN 3653:2010 is associated with several key standards:
- EN 2133: Specifies cadmium plating for steels, copper, and nickel alloys to protect against corrosion.
- EN 2424: Defines marking requirements for aerospace products ensuring traceability.
- EN 2491: Covers molybdenum disulphide dry lubricant coatings for optimal thread performance.
- EN 2542 & EN 2543: Detail material requirements for steel used in nuts meeting aerospace tensile properties.
- EN 9100: Aerospace quality management system requirements supporting approved manufacturing.
- EN 9133: Procedures for qualifying aerospace standard part products.
- ISO 5855-2: Limits dimensions of aerospace bolts and nuts to maintain consistency.
- ISO 5858: Procurement specifications for self-locking nuts rated for maximum operating temperatures ≤ 425 °C.
- ISO 8788: Defines tolerances for form and position of metric nuts in aerospace applications.
Summary
