Overview
EN 2546:2006 - Aerospace series - specifies the characteristics and dimensions of lock washers with radial serrations made from corrosion-resisting steel, passivated, and intended primarily for flight control rods. The standard defines the configuration (figures), dimensional tables, material and surface-treatment requirements, marking and designation, and qualification requirements to ensure reliable immobilisation of rod ends while allowing precise positional adjustment.
Key topics and requirements
- Purpose: Lock washers with radial serrations are intended to immobilise the rod end relative to the rod body while permitting fine positional adjustment of flight control linkages.
- Dimensions and mass: Detailed Figures 1–3 and Tables 1–2 provide nominal dimensions, tolerances and masses for diameter codes (examples include codes 08–16). The standard covers both the rod-body side element (Code A) and the rod-end side element (Code B) and the assembled washer (Code C).
- Surface roughness: Specified surface finish Ra = 3.2 µm.
- Material: Corrosion-resisting steels in accordance with EN 2540 or EN 2538 (the latter noted; EN 2538/EN 2540 as applicable; EN 2538 is referenced for FE-PM3801, EN 2540 for FE-PM3902).
- Surface treatment: Passivation per EN 2516 to ensure corrosion resistance and compatibility with aerospace requirements.
- Marking and designation: Prescribed identity block format (e.g., “WASHER LOCK EN2546A08”) and requirement that marking be indelible where possible without impairing function. Packaging and individual items must be marked.
- Qualification and quality: Qualification of parts follows EN 9133 (aerospace quality management/qualification procedure for standard parts).
Applications and users
- Primary application: Flight control rod assemblies in aircraft and other aerospace mechanisms where secure, adjustable locking is required.
- Who uses EN 2546:2006:
- Aerospace designers and mechanical engineers specifying flight control hardware
- Fastener and washer manufacturers producing serrated, passivated lock washers
- Quality, procurement and certification teams ensuring parts meet aerospace standardization
- Maintenance and overhaul organisations replacing or verifying control rod components
- Practical benefits: Standardized dimensions and materials promote interchangeability, predictable performance, corrosion resistance, and simplified procurement across CEN member states.
