Overview

EN 2944:2018 is a European standard developed by CEN that specifies the characteristics of self-locking, helical coil inserts made from corrosion-resisting steel FE-PA3004 (NI PH2801) designed for aerospace applications. These inserts feature a tanged insertion drive and are optimized to withstand maximum test temperatures up to 350 °C. As part of the aerospace series, this standard ensures the high reliability and durability required for critical aerospace fastening systems.

The standard is vital for manufacturers, engineers, and quality assurance professionals involved in aerospace component design and assembly, providing detailed specifications on dimensions, materials, identification, marking, and performance requirements.

Key Topics

  • Insert Characteristics
    The standard details the configuration, dimensions, tolerances, and masses of helical coil inserts with self-locking capabilities tailored for aerospace screw threads.

  • Material Specifications
    Inserts are made from corrosion-resistant steel FE-PA3004 (X10CrNi18-09), compliant with EN 2947, ensuring durability in harsh environmental conditions typical of aerospace applications.

  • Temperature Resistance
    Parts are tested and rated for service up to 350 °C, addressing thermal stability requirements in aerospace environments.

  • Design and Dimensions
    Includes precise measurements, coil counts, and dimensional tolerances for different insert sizes, matched with their corresponding screw threads based on ISO 5855-2 standards.

  • Marking and Identification
    Parts are identified by a blue color mark without chlorine-based constituents, supporting traceability and compliance with aerospace product marking standards (EN 2424).

  • Installation and Assembly
    References to additional standards such as EN 2945 and EN 3044 provide guidance on assembly procedures and installation hole design, facilitating correct and safe insertion.

Applications

  • Aerospace Fastening Systems
    Used extensively for repair and manufacture of threaded joints in aircraft and spacecraft components where thread integrity and self-locking properties are critical.

  • High-Temperature Environments
    Suitable for aerospace components exposed to elevated temperatures up to 350 °C such as engine parts, fuel systems, and landing gear assemblies.

  • Corrosion-Resistant Thread Inserts
    Ideal for applications where enhanced corrosion resistance extends component life and reliability in aggressive environmental conditions.

  • Precision Aerospace Manufacturing
    Ensures consistency and quality in aerospace assembly lines by standardizing insert dimensions, material requirements, and performance.
