Overview - EN 4009:2004 (Aerospace bolts, Inconel 718 / NI‑PH2601)

EN 4009:2004 specifies the characteristics of double hexagon head bolts with close tolerance shank and medium length thread made from the heat‑resisting nickel‑base alloy NI‑PH2601 (Inconel 718) for aerospace use. The material classification is 1 550 MPa (ambient) tensile strength and parts are assessed for service up to 650 °C. The standard is part of the CEN aerospace series and supersedes the 2003 edition.

Key topics and technical requirements

• Geometry and tolerances: Defines bolt configuration, dimensions, tolerances and masses (see Figure 1, Tables 1–2). Dimensions are metric and given in millimetres.
• Threads and drives:
  • MJ (aerospace) thread profiles (limit dimensions referenced to ISO 5855‑2).
  • Rolled external threads conforming to ISO 3353‑1.
  • Bihexagonal (double hexagon) wrenching configuration in accordance with ISO 4095.
• Material and heat treatment:
  • Parent material reference: NI‑PH2601 (Inconel 718) per EN 2952 / EN 3666.
  • Final heat treatment shall meet EN 3666 (solution treated and cold worked, with the higher strength range indicated).
• Mechanical classification: Minimum tensile strength 1 550 MPa at ambient; maximum test/usage temperature 650 °C.
• Designation and marking:
  • Example designation: BOLT EN4009‑080050 (standard number + thread code + length code).
  • Marking follows EN 2424 (style A).
• Technical specification and conformity: References EN 3833 for the technical specification and test requirements.

Applications and practical value

• Intended for critical aerospace fastenings where high tensile strength and elevated temperature resistance are required.
• Typical uses include components exposed to high temperatures and demanding mechanical loads (e.g., hot sections of engines, high‑temperature airframe joints and propulsion system assemblies).
• Helps manufacturers, designers and procurement ensure interchangeability, traceability and consistent mechanical performance of Inconel 718 bolts.

Who uses this standard

• Aerospace design and stress engineers specifying fasteners.
• Fastener manufacturers and heat‑treatment shops producing NI‑PH2601 bolts.
• Quality assurance, procurement teams and maintenance/repair organizations verifying part conformity.
• Certification and regulatory authorities assessing component compliance.
