Overview

prEN 2942:2022 (CEN) defines the characteristics and requirements for aerospace series self‑locking inserts with MJ screw threads - specifically helical coil, tanged insertion drives fabricated from the heat‑resisting nickel‑base alloy NI‑PH2801 (Inconel X750) and silver plated. The draft standard covers configuration, dimensions, material, surface treatment and marking for inserts intended for aerospace use. The maximum test temperature for these inserts is 550 °C.

Key topics and technical requirements

  • Scope and purpose: Specifies self‑locking helical coil inserts (MJ thread series) with tanged insertion drives in NI‑PH2801, silver plated for aerospace applications.
  • Materials: Base material required by EN 3018 (NI‑PH2801 / Inconel X750, cold drawn wire).
  • Surface treatment: Electrolytic silver plating per EN 2786, with plating thickness 2–5 μm.
  • Dimensions and tolerances: Detailed configuration, dimensions, masses and tolerances are provided (metric, in millimetres) and apply after silver plating; roughness Ra values apply before plating. MJ thread limits reference ISO 5855‑2.
  • Design and installation: Layouts, lead‑in, coil counts and installation dimensions are provided; see referenced design standards EN 3044 for installation holes and EN 2945 for assembly procedures.
  • Marking and designation: Marking rules referenced to EN 2424 (style G, with optional style F); designation format and optional code I9005 described.
  • Technical specification & quality: Product technical specification per EN 2943. Manufacturers must operate approved aerospace production organizations and maintain an aerospace quality system (e.g., EN 9100 or equivalent). Qualification procedures (e.g., EN 9133) apply unless otherwise agreed.

Applications and users

  • Typical users: aerospace fastener manufacturers, design and mechanical engineers, procurement specialists, quality/inspection teams, and maintenance organizations.
  • Practical use cases: specifying and procuring high‑temperature resistant, self‑locking threaded inserts for aerospace assemblies where a combination of MJ screw thread, helical coil locking, and Inconel X750 heat resistance is required. Suitable for components exposed to elevated service or test temperatures (up to 550 °C).

Related standards

  • EN 3018 - NI‑PH2801 material (Inconel X750)
  • EN 2786 - Electrolytic silver plating of fasteners
  • EN 2943 - Inserts, MJ and M screw threads - Technical specification
  • EN 3044 / EN 2945 - Design and assembly procedures for helical coil inserts
  • ISO 5855‑2 - MJ threads (limit dimensions)
  • EN 2424, EN 9100, EN 9133

This summary helps engineers and procurement teams quickly identify compliance, material and surface requirements, and quality expectations when specifying self‑locking, silver‑plated MJ helical coil inserts in Inconel X750 (NI‑PH2801) under prEN 2942:2022.
