Overview
EN 3539:2010 is a European standard developed by CEN, specifying requirements for aerospace series anchor nuts that are self-locking, fixed, and feature a one lug design with a counterbore. These nuts are manufactured from heat resisting steel and are lubricated with molybdenum disulphide (MoS2) to withstand elevated temperatures. The standard classifies these nuts for strength at 1,100 MPa at ambient temperature and operational temperature resistance up to 315 °C.
This standard is critical in aerospace and defense industries for ensuring the reliability and safety of threaded fasteners that operate under demanding mechanical and thermal conditions. It harmonizes specifications, dimensions, materials, and performance criteria for these specialized nuts, supporting international compatibility and quality assurance.
Key Topics
Scope and Application
Defines characteristics, materials, lubrication, and performance for one lug counterbored fixed anchor nuts designed with a self-locking feature via an out-of-round upper portion.Material Specifications
Utilizes heat resisting steels complying with EN 2398, EN 2399, EN 3638, or EN 3639, providing high tensile strength and thermal resistance.Lubrication
MoS2 (molybdenum disulphide) coating ensures reduced friction and wear at high temperatures, maintaining locking performance.Mechanical Classification
Nuts are capable of withstanding 1,100 MPa tensile strength at room temperature, aligning with aerospace bolt strength classes.Temperature Rating
Certified to endure up to 315 °C without losing mechanical or locking properties, critical for aerospace environments.Dimensional and Form Tolerances
Follows ISO 3168 and ISO 8788 standards for geometric accuracy, thread dimensions, and form tolerances to ensure compatibility and performance.Marking and Traceability
Requires standardized marking per EN 2424 for product identification and quality control.Compliance and Quality Management
Manufacturers must meet EN 9100 quality management system requirements and product qualification rules under EN 9133.
Applications
EN 3539:2010 nuts are specifically designed for:
Aerospace Fastening Systems
Used in aircraft, spacecraft, and related defense equipment where high mechanical loads and thermal exposure occur.High-Temperature Environments
Suitable for assembly points experiencing sustained temperatures up to 315 °C, such as engine mounts and exhaust systems.Self-Locking Assembly
Ensures secure fastening in vibration-intensive and harsh service conditions without additional locking components.Maintenance and Repair
Conforms to international aerospace standards, enabling interchangeability and maintenance efficiency in aviation platforms.
