General Information

Overview
EN 2889:2006 (CEN) specifies the characteristics and procurement requirements for aerospace series metric bolts with a normal hexagon head, coarse-tolerance normal shank and short thread, manufactured in alloy steel and cadmium plated. Bolts covered by this standard are classified 900 MPa (ambient)/235 °C, intended for high-strength aerospace applications where consistent dimensions, surface treatment and traceable quality are required.
Key normative references used by EN 2889 include ISO 3193 (dimensions), ISO 3353-1 (rolled external threads), ISO 5855-2 (MJ thread limits), ISO 7689 (procurement specification, modified), ISO 7913 (form and position tolerances), EN 2133 (cadmium plating), EN 2424 (marking) and EN 9100 (manufacturer approval / quality systems).
Key Topics
- Configuration and dimensions: Bolts conform to ISO 3193 dimensional rules; dimensions are specified in millimetres and apply after surface treatment.
- Materials: Alloy steel per TR 3775 with minimum tensile classification 900 MPa at ambient temperature.
- Surface treatment: Cadmium plating in accordance with EN 2133. A specified plating thickness of 8 µm to 14 µm applies to all surfaces contactable by a 20 mm diameter ball; continuous cadmium plating is required elsewhere. A black colour option exists (code B) but with modified corrosion requirements.
- Mechanical / inspection requirements: ISO 7689 applies with modifications:
- Hardness at the end of the thread: 269–321 HBS (Brinell) or 284–340 HV30 (Vickers).
- Acceptable quality level (AQL) for defect classification is modified to 1% (replacing 0.065%).
- Manufacturer approval follows EN 9100.
- Marking & designation: Example designation format - BOLT EN2889 D 080 060 B. Hole and locking codes include:
- Lockwire: H
- Split pin: D
- Lockwire and split pin: C
- No hole: - (hyphen)
Applications
EN 2889 bolts are specified where high static strength and reliable surface protection are needed in aerospace structures and assemblies. Typical uses include:
- Structural fastenings in airframe assemblies
- Maintenance and repair parts where interchangeability and traceability are required
- Environments requiring cadmium corrosion protection and controlled temperature exposure up to the standard’s surface-treatment limit (235 °C)
The standard supports procurement, inspection and manufacturing controls by aligning dimensions and tolerances with aerospace thread and tolerance ISO standards while prescribing plating and hardness checks.
