General Information

Overview
EN 2885:2023 is a CEN (ASD‑STAN) aerospace standard that defines the characteristics of a specific aerospace screw: pan head, offset cruciform recess, coarse‑tolerance normal shank, short thread, made in alloy steel and cadmium plated. It applies to the MJ metric thread series and is classified 900 MPa (minimum tensile strength at ambient temperature) / 235 °C (maximum service temperature determined by surface treatment). This edition supersedes EN 2885:1996.
Key topics and technical requirements
- Configuration, dimensions and masses: Sizes and mass data are specified (see Figure 1 / Table 1 in the standard) for diameter codes 030–120 (MJ3×0.5 up to MJ12×1.25). Dimensions/tolerances are in millimetres and apply after surface treatment.
- Threads and tolerances: Threads conform to MJ thread limits (ISO 5855-2) and lead/runout/threads geometry references such as ISO 3353‑1. Form and position tolerances follow ISO 7913.
- Material class: Alloy steel per TR 3775, strength class 900 MPa.
- Surface treatment / plating: Cadmium plating per EN 2133. For surfaces contactable by a 20 mm ball, cadmium deposit thickness is 8 µm to 14 µm; continuous deposit required elsewhere. Black colour option: code B. Break sharp edges to 0.1–0.4 mm.
- Mechanical properties: Hardness at end of thread - Brinell 269–321 HBS; Vickers 284–340 HV30.
- Drive and marking: Drives per ISO 14275 (ribbed, code R) and ISO 14276 (unribbed, code A). Marking requirements reference EN 2424; diameter style codes identified.
- Quality and manufacturer approval: Manufacturer must be an approved aerospace production organisation and maintain a recognized quality system (e.g., EN 9100).
- Inspection / acceptance: Classification of defects updated: AQL replaced by 1%. Several previous requirements were removed (e.g., qualification of screws, cold rolling, tensile/double shear/tension fatigue tests).
Applications and who uses this standard
- Aerospace design and structural engineers specifying fasteners where high strength (900 MPa) and cadmium corrosion protection are required.
- Procurement and quality managers validating supplier conformity, marking, and traceability.
- Fastener manufacturers producing MJ‑series alloy‑steel screws with cadmium plating to aerospace practice.
- Maintenance, repair and overhaul (MRO) organizations selecting approved replacement parts for airframe and equipment assemblies.
