Overview
EN 4459:2005 is a European standard developed by CEN for the aerospace industry, focusing on the specification and application of studs made from titanium alloy TI-P64001. These studs incorporate a serrated locking ring made from corrosion-resistant steel, providing enhanced security and reliability for critical aerospace assemblies. The standard outlines the use, installation hole dimensions, and necessary considerations for component salvage, ensuring that aerospace components maintain structural integrity and can be repaired efficiently when needed.
Key Topics
Stud Material and Construction
EN 4459:2005 specifies that the studs are made from titanium alloy TI-P64001, chosen for its high strength-to-weight ratio and corrosion resistance. The serrated locking ring, produced from corrosion-resistant steel, provides a secure anti-rotation mechanism.Installation Guidelines
The standard details the installation process, including hole dimensions, the importance of serrated holes in hard materials, and ensuring a reliable assembly. It highlights that the assembly is intended to be inseparable; removal typically requires destroying the locking ring and stud.Usage Parameters
- Suitable for both soft (e.g., light alloys) and hard (e.g., nickel or titanium alloys) base materials
- Compatible with blind or through tapped holes
- Designed for use with MJ thread nuts as per ISO 5855-2
- Not suitable for applications involving shear loads or rotating parts
Component Salvage Provision
EN 4459:2005 includes recommendations for salvaging components where holes may have been damaged or misaligned, emphasizing the economic and structural considerations unique to expensive or mission-critical aerospace components.Designation and Drawing
The standard prescribes a clear designation system and requirements for drawing presentation to ensure consistency in documentation and manufacturing.
Applications
EN 4459:2005 is primarily utilized in:
Aerospace Fastening Systems
Used for securing structural and sub-structural components in aircraft and aerospace vehicles, particularly where high strength, corrosion resistance, and reliable anti-rotation locking are required.Maintenance and Repair
Essential in aerospace maintenance operations, allowing for effective salvage of high-value components and ensuring ongoing airworthiness.Component Design and Integration
Informs engineering teams during the design phase, helping ensure that fastener selection, installation methods, and salvage options meet the rigorous standards of aerospace applications.Quality Assurance Processes
Provides a reference for inspection and quality control organizations to verify correct installation and suitability in aerospace assemblies.
Related Standards
To achieve maximum compliance and interoperability, EN 4459:2005 should be used alongside the following standards:
- EN 4421: Aerospace series - Studs, in titanium alloy TI-P64001, MoS2 coated, with serrated locking ring in corrosion resisting steel – Strength class: 1 100 MPa
