General Information

Overview
EN 2884:2024 specifies the characteristics of aerospace series pan head screws with an offset cruciform recess, coarse tolerance normal shank and short thread, manufactured in titanium alloy, anodized and MoS2 (molybdenum disulphide) lubricated. Classified as 1 100 MPa (ambient tensile strength) / 315 °C (maximum service temperature determined by surface treatment), this CEN standard defines geometry, surface finish, materials and manufacturing/quality requirements for high‑performance aerospace fasteners.
Key topics
- Scope and classification
- Fastener type: pan head, offset cruciform recess, short thread, coarse tolerance normal shank.
- Material class: titanium alloy, strength class 1 100 MPa; max temperature 315 °C.
- Dimensions and threads
- Thread series and diameters follow MJ threads (ISO 5855-2); sizes in the standard range from MJ3 up to MJ12.
- Dimensional tolerance and form/position tolerances referenced to ISO 7913.
- Surface treatment and lubrication
- Anodizing per ISO 8080 for titanium/titanium alloys.
- MoS2 dry lubricant per TR 4070 and applied according to EN 2491 (5–10 µm).
- Surface roughness
- Specified Ra max values: thread 0.8 µm; bearing surfaces 1.6 µm; other surfaces 3.2 µm (values apply prior to treatment).
- Marking and designation
- Marking requirements reference EN 2424; drive codes follow ISO 14275 / ISO 14276.
- Manufacturer and qualification
- Manufacturers must be approved aerospace production organizations with an aerospace quality system (e.g. EN 9100).
- Product qualification and tests per ISO 9152 and qualification procedures such as EN 9133 where applicable.
Applications
EN 2884:2024 is intended for aerospace sectors where a combination of high strength, corrosion resistance, light weight and controlled friction is required. Typical applications include:
- Structural assemblies in aircraft and spacecraft where titanium fasteners reduce weight.
- High‑temperature or thermally cycled zones where anodized surface and lubricant stability (up to 315 °C) are critical.
- Precision aerospace components requiring defined surface roughness, drive configuration and reproducible torque behavior.
Users: aerospace design engineers, fastener manufacturers, procurement/specification writers, quality managers, maintenance and MRO teams.
