Overview

EN 4130:2009 is a CEN aerospace standard that specifies the characteristics, designation, marking and technical requirements for normal hexagonal‑head bolts with a coarse‑tolerance normal shank and medium length MJ threads, manufactured in titanium alloy and finished with aluminium IVD (ion vapour deposition) coating. The parts are classified as strength class 1100 MPa (minimum tensile at ambient) with a service temperature guidance of 425 °C (maximum temperature the bolt can withstand without continuous change, surface‑treatment dependent).

Key topics and technical requirements

• Scope and configuration: Dimensional requirements and tolerances are given in millimetres and conform to ISO 3193 (MJ threads) and ISO 5855‑2 limit dimensions. Detailed size tables define diameter, thread and length codes.
• Material: Titanium alloys in accordance with TR 3775 for the 1100 MPa classification.
• Surface treatment: Aluminium IVD per MIL‑DTL‑83488D, Type II, Class 3 with a coating thickness of 4 µm to 12 µm. After deposition a mechanical blast and chromate conversion coating (within 24 h) are required; optional lubrication with cethylic alcohol (code E).
• Form & positional tolerances: See ISO 7913.
• Marking & designation: Standardized designation format (example: EN4130H050040E) and marking rules referencing EN 2424.
• Quality and procurement: Manufacturer approval and qualification references point to EN 9100 and EN 9133; procurement and testing per ISO 9152 (with exceptions noted in EN 4130).

Applications and practical value

• Used where high strength, lightweight and corrosion‑resistant fasteners are required in aerospace structures: airframe assemblies, engine mounts, landing gear interfaces and other critical joints where titanium fasteners are preferred.
• The aluminium IVD coating provides wear and corrosion protection while maintaining electrical and environmental performance suited to aerospace environments.
• Engineers, procurement specialists and quality managers use EN 4130 to:
  • Specify compliant titanium hex‑head bolts in design documents and purchase orders.
  • Ensure consistent manufacturing, inspection and acceptance criteria for aerospace fasteners.
  • Match thread, dimensional and coating requirements with component compatibility and service temperature specifications.

Who should use this standard

• Aerospace design and structural engineers
• Fastener manufacturers and coating suppliers
• Procurement and specifications teams in OEMs and MRO organizations
• Quality assurance and testing laboratories
