General Information
Overview
EN 3858:2002 specifies the required characteristics of thrust wires in steel FE-PA 13 for use with 60° spherical pipe couplings manufactured in titanium alloy TI‑P64001. Intended for aerospace fluid systems and components, the standard defines configuration, material reference, surface coating practice and designation conventions. NOTE: this standard is intended to be used together with EN 3856 (swivel nuts for thrust wire).
This standard supports consistent production, traceability and quality assurance across suppliers and OEMs by providing a common set of requirements for these small but critical components.
Key Topics
- Configuration, dimensions and tolerances: Dimensions and tolerances are specified (in millimetres) and apply before lubrication. A table of diameter codes and corresponding masses is provided.
- Material: Thrust wires are specified to be made in accordance with EN 2573 (steel FE‑PA 13, softened and lightly drawn, wire diameters as covered in that reference).
- Surface coating: Coating guidance references EN 2491 (molybdenum disulphide dry lubricant coating methods) where applicable.
- Designation and marking: A clear designation format is given (example: THRUST WIRE EN 3858 -100) and marking should follow EN 2424 style G to ensure product identification and traceability.
- Quality assurance: Quality system requirements and approval of manufacturer quality systems are referenced to EN 2000.
Applications
EN 3858:2002 is directly applicable to aerospace system designers, component manufacturers, procurement specialists and maintenance organizations who need to:
- Ensure interchangeability of thrust wires used in 60° spherical titanium couplings across suppliers.
- Maintain consistent fit, lubrication and surface treatment compatible with the coupling design and installation practices.
- Implement traceability and marking practices that satisfy aerospace quality systems and regulatory expectations.
- Facilitate supplier approval and incoming inspection by referencing standardised dimensions, material grade (FE‑PA 13) and accepted coating methods.
Typical use cases include hydraulic and fuel line couplings on aircraft where small-diameter thrust wires secure swivel nut interfaces in spherical pipe fittings.
