EN 2556:1992 - Aerospace series - Rivets, solid, 100° normal countersunk head with dome, in aluminium alloy 5056A, anodized or chromated, inch based series

Overview

EN 2556:1992 (CEN) is an aerospace series standard that specifies the characteristics of solid rivets with a 100° normal countersunk head with dome, manufactured in aluminium alloy 5056A, finished by anodizing or chromating, and supplied in an inch-based series. The standard also limits the rivet’s maximum continuous operating temperature to 120 °C. It is intended for aerospace applications where flush, corrosion-resistant aluminium rivets are required.

Key topics and requirements

The standard defines essential characteristics and requirements for this rivet type, including:

  • Head geometry: 100° normal countersunk head with a dome profile (flush mounting).
  • Material: Aluminium alloy 5056A, selected for its corrosion resistance and suitability in aerospace structures.
  • Surface treatment: Acceptable finishes are anodized or chromated to enhance corrosion protection and paint adhesion.
  • Size system: Inch-based series of diameters and lengths for compatibility with imperial tooling and assemblies.
  • Temperature rating: Maximum operating temperature of 120 °C, establishing service limits for materials and finishes.
  • Characteristic categories typically covered (by standards of this type):
    • Dimensional specifications and tolerances
    • Material and metallurgical requirements
    • Surface treatment and corrosion protection
    • Identification and marking
    • Inspection, acceptance criteria and basic testing

(EN 2556:1992 specifies the rivet characteristics; consult the full document for exact dimensional tables, tolerances and testing procedures.)

Applications

This standard is targeted at aerospace and aviation sectors where lightweight, flush-bodied fastenings are required, including:

  • Aircraft skin and panel fastening where a flush finish is critical for aerodynamics
  • Interior and secondary structural assemblies in civil and military aircraft
  • Repair, overhaul and maintenance operations requiring replacement rivets that meet aerospace specifications
  • Procurement and quality control for OEMs, MROs and parts suppliers needing consistent material, finish and temperature performance

Users include design engineers, manufacturing engineers, quality inspectors, procurement specialists and maintenance technicians working with aerospace fasteners.

Related standards

Standards users often reference EN 2556 alongside other aerospace fastener and aluminium alloy standards, such as:

  • Other EN aerospace rivet series and fastener standards
  • International aerospace fastener specifications (e.g., NAS/AMS) and relevant ISO standards for fasteners and aluminium alloys

For exact dimensions, tolerances, testing methods and acceptance criteria, obtain the full EN 2556:1992 document from the national standards body or CEN.
