Overview

EN 4174:2006 is a CEN aerospace standard that specifies the characteristics of swage collars, shear‑type, manufactured in aluminium alloy 2024, in a metric series and finished by anodizing or chromate conversion. The standard applies to collars intended for aerospace assemblies with a maximum operating temperature of 120 °C. Dimensions, tolerances and marking rules are defined so collars are interchangeable and suitable for critical fastening applications.

Key topics

  • Material: Aluminium alloy 2024 in accordance with referenced aerospace material documents (see EN 2319 / EN 2320 for bar specifications).
  • Geometry & tolerances: Collar dimensions, diameters and heights are given as metric values; tolerances apply after surface treatment. Diameter codes (e.g., 040, 050 … 100) and related dimensional data are provided in the standard. Approximate masses per 1 000 pieces are listed for planning and procurement.
  • Surface treatment: Finishes include chromic anodizing (silver) and clear chromate conversion coatings; surface treatments are referenced to EN 2284 and EN 2437. Lubrication guidance (cetyl alcohol, MIL‑L‑87132) is included where applicable.
  • Marking & identification: Marking style follows EN 2424 (style F). Example identity format: “COLLAR EN4174 A040” (standard number + finish code + diameter code). An optional supplementary code (e.g., I9005) may be used.
  • Related technical specification: For detailed performance and installation context, EN 4174 cross‑references EN 4176 (lockbolts and collars technical specification).

Applications

  • Used by aerospace OEMs and Tier‑1/2 suppliers as locking collars for swage (crimp/press) fastening systems where shear‑type collars are required.
  • Suited for airframe and structural assemblies, equipment housings and other aerospace components operating up to 120 °C.
  • Relevant for procurement, quality assurance, design engineering and maintenance teams specifying interchangeable fastener collars.

Who uses this standard

  • Aerospace design and stress engineers selecting fasteners.
  • Fastener manufacturers and swaging tool suppliers producing metric shear collars.
  • Quality and inspection personnel verifying dimensional and marking compliance.
  • Procurement and regulatory teams ensuring parts meet recognized European aerospace standards.
