Overview

EN 2942:1998 (CEN) defines the characteristics of self-locking, helical coil screw-thread inserts manufactured from the heat-resisting nickel base alloy NI-PH2801 (commonly referenced as Inconel X750), with a silver plated finish. This aerospace series standard applies to inserts intended for high-temperature aerospace environments and includes a maximum test temperature of 550°C.

This standard is relevant to engineers, procurement specialists, and quality teams working on aerospace fasteners and threaded assemblies where elevated temperature performance and locking capability are required.

Key Topics

  • Material specification: Heat-resisting nickel base alloy NI-PH2801 (Inconel X750).
  • Product form: Helical coil, self-locking screw-thread inserts suitable for aerospace threaded connections.
  • Finish: Silver plated surface treatment.
  • Thermal rating: Maximum test temperature specified at 550°C.
  • Scope and applicability: Focused on characteristics needed for reliable thread reinforcement and self-locking performance in aerospace applications.

EN 2942:1998 emphasizes consistent material selection and surface treatment to support high-temperature performance and durability. The standard helps ensure interchangeability and predictable behavior of inserts across aerospace designs.

Applications

These self-locking, helical coil inserts are typically used where a combination of the following is required:

  • High-temperature thread reinforcement in aerospace structures and engine components.
  • Vibration-resistant locking where threaded joints must retain preload under dynamic loading.
  • Corrosion and oxidation resistance provided by the nickel-base alloy and silver plating in demanding environments.

Typical application areas include threaded repair and reinforcement, installation in high-temperature alloy housings, and assemblies where secure locking and thermal stability are essential. While EN 2942:1998 is specific to NI-PH2801 (Inconel X750) silver plated inserts, the practical value lies in standardizing the characteristics that designers and manufacturers rely on for safe, repeatable performance in critical aerospace hardware.

Related Standards

  • Other aerospace fastener and insert standards that address different alloys, plating options, or mechanical characteristics (refer to the relevant CEN or industry documents for matching requirements).
  • Standards covering thread forms, installation tools, and quality assurance for screw-thread inserts and threaded assemblies.

For specification and procurement, reference EN 2942:1998 by designation to ensure material, finish, and thermal capability align with project requirements. This standard supports compatibility across suppliers and promotes consistent performance for high-temperature aerospace threaded connections.
