Overview

EN 4124:2018 is a European standard developed by CEN that specifies the requirements for self-locking shank nuts made from a heat-resisting nickel base alloy NI-PH1302 (commonly known as Waspaloy) with silver plating on the thread. These nuts are designed for aerospace applications and intended for use in 60° cone holes (swage). The standard ensures high-performance fasteners are available with the ability to withstand a minimum tensile stress of 1,210 MPa at ambient temperature and operate safely at temperatures up to 730 °C.

This standard supersedes EN 4124:2004 and provides detailed specifications on dimensions, material composition, surface treatment, marking, and technical requirements tailored for critical aerospace environments where heat resistance and mechanical integrity are mandatory.

Key Topics

  • Material Specification: The nuts are manufactured from NI-PH1302 (Waspaloy), a nickel-based alloy known for excellent heat resistance and mechanical strength, meeting criteria defined in EN 2959 and EN 3220.
  • Self-Locking Feature: The nuts have an out-of-round thread profile in the self-locking zone, allowing them to maintain locking capability without additional locking elements.
  • Silver Plating: Thread surfaces are electrolytically silver plated per EN 2786 to enhance corrosion resistance and ensure reliable fastening performance.
  • Dimensional Tolerances: Precise dimensions for shank nuts are specified, including thread size, diameter, and length; all dimensions are given after plating to maintain accuracy.
  • Temperature Classification: The standard classifies the nuts for use up to 730 °C, ideal for aerospace environments involving high thermal stress.
  • Marking and Traceability: Marking specifications are given under EN 2424 to ensure product traceability and compliance.

Applications

EN 4124:2018 nuts are primarily intended for use in the aerospace industry, including:

  • Aircraft and Spacecraft Assembly: Used in critical structural connections where heat resistance and secure fastening are mandatory.
  • High-Temperature Components: Fastening applications near engines, turbines, and exhaust systems exposed to elevated temperatures.
  • Aerospace Manufacturing: Component suppliers and manufacturers seeking standardized fasteners for safety and performance compliance.
  • Defense Aerospace: Military aerospace systems requiring reliable, self-locking fasteners under harsh operating conditions.

These shank nuts offer enhanced durability and locking integrity, addressing demanding environments typical in aerospace applications.

Related Standards

  • EN 2959: Covers the heat-resisting alloy NI-PH1302 material used for forging fasteners.
  • EN 2786: Specifies the electrolytic silver plating process applied to the threads.
  • EN 3005: Provides technical specifications for self-locking nuts made from NI-PH1302.
  • ISO 5855-2: Establishes limit dimensions for MJ threads on bolts and nuts, referenced for sizing accuracy.
  • EN 2424: Defines the marking system for aerospace products ensuring traceability and compliance.

By conforming to EN 4124:2018, manufacturers and aerospace engineers ensure the use of high-quality, reliable self-locking shank nuts that meet stringent aerospace industry requirements for performance, safety, and consistency under severe operating conditions.
