SIST EN 4172:2008 - Aerospace series - Lockbolts, protruding head, sheartype, close tolerance, in titanium alloy TI-P64001, anodized, metric series - Classification: 1 100 MPa (at ambient temperature) / 315 °C

Overview

EN 4172:2006 defines the characteristics of aerospace lockbolts - protruding head, shear-type, close tolerance - manufactured in titanium alloy TI‑P64001, anodized, metric series. The standard is intended for structural aerospace use and carries the material classification: 1 100 MPa (at ambient temperature) / 315 °C. Both versions - with pintail (version P) and without pintail (version S) - are statically and dynamically equivalent when installed. These lockbolts are intended to be used with collars conforming to EN 4174 or EN 4175.

Key Topics

  • Scope and classification: Defines intended aerospace applications and the tensile/temperature classification (1 100 MPa / 315 °C).
  • Configuration and dimensions: Metric geometry, close-tolerance dimensions and mass values are specified (diameter and length codes, tolerances apply after surface treatment).
  • Versions: Version P (pull-type with pintail) and version S (stub-type without pintail) - both functionally equivalent in service.
  • Materials: Titanium alloy per TR 3775 (TI‑P64001) - strength class as above.
  • Surface treatment and lubrication:
    • Anodizing per EN 2808 (titanium anodizing).
    • Lubrication guidance referencing MIL‑L‑87132 (cetyl alcohol).
  • Marking and identification: Marking style per EN 2424, and prescribed description/identity block formats (example: EN4172P040–140G).
  • Technical specification / procurement: Detailed technical requirements and test/spec references are covered and cross-referenced to EN 4176 for related lockbolt specifications.
  • Normative references: Lists the essential standards and technical reports needed to apply EN 4172.

Applications

Who uses EN 4172:2006 and why:

  • Aerospace designers & structural engineers specifying high-strength, lightweight shear fasteners for airframe assemblies.
  • Procurement and quality teams ensuring purchased fasteners meet titanium TI‑P64001 material, anodizing, marking and tolerance requirements.
  • Fastener manufacturers and suppliers producing metric-series lockbolts to aerospace tolerances and surface finishes.
  • Maintenance, repair and overhaul (MRO) operations that replace or verify OEM-standard lockbolts. Practical uses include fastening shear-loaded joints in airframes and aircraft subsystems where titanium’s high strength-to-weight and temperature resistance are required.
