Overview

EN 2550:1992 - Aerospace series - specifies the characteristics of solid rivets with a 100° normal countersunk head, manufactured in aluminium 1050A, presented in an inch based series. Published by CEN, this aerospace standard defines the basic requirements for rivets intended for applications where a flush, countersunk finish is required and where the maximum operating temperature does not exceed 120 °C.

Key topics and requirements

The standard focuses on the essential characteristics needed to ensure interchangeability and reliable performance in aerospace use:

  • Head geometry: 100° normal countersunk head for flush installation and aerodynamic surfaces.
  • Material: Aluminium 1050A (commercially-pure aluminium grade specified by the standard).
  • Dimensional series: Inch-based sizes and tolerances to match legacy and imperial-design assemblies.
  • Temperature rating: Maximum continuous operating temperature limited to 120 °C.
  • Characteristic definition: Specifies the rivet characteristics (dimensions, material designation and intended use) required for procurement and specification in aerospace manufacturing and maintenance.

(Note: EN 2550 defines the characteristics - detailed tests, exact dimensions or mechanical property values should be verified in the full published standard.)

Applications

EN 2550 rivets are used where a flush surface and lightweight fastening are required under moderate temperature conditions:

  • Aircraft structural assemblies requiring countersunk, flush fastenings (skins, fairings, control surfaces).
  • Aerospace interior and secondary structural components where aluminium fasteners are suitable.
  • Maintenance, repair and overhaul (MRO) operations needing inch-based rivet sizes and compatible material.
  • Fastener suppliers and procurement teams specifying aluminium countersunk rivets for aerospace use.

Who uses this standard

  • Aerospace design and structural engineers selecting rivet types for assemblies.
  • Procurement and quality managers specifying compliant fasteners.
  • MRO technicians and inspectors ensuring parts meet required characteristics.
  • Fastener manufacturers and distributors producing or supplying inch-based aluminium rivets.

Related standards

  • Other EN aerospace fastener standards covering different rivet head forms, materials and metric series.
  • Aluminium material specifications that define composition and properties for aluminium 1050A.
  • Regulatory and certification guidance (airworthiness authorities) for fasteners and repairs.

EN 2550 is essential when specifying solid, 100° countersunk aluminium rivets in inch sizes for aerospace applications where temperatures remain at or below 120 °C.
