Overview
EN 2888:2006 is a European aerospace standard published by the Comité Européen de Normalisation (CEN) that defines the specifications for metric bolts used in aerospace applications. This standard specifically covers normal hexagon head bolts with a coarse tolerance, normal shank, and short thread configuration. The bolts are made from corrosion-resisting steel and are passivated for enhanced durability. They are classified to withstand a minimum tensile strength of 600 MPa at ambient temperature and retain their mechanical properties up to 425 °C.
Developed to meet the stringent requirements of aerospace manufacturing and maintenance, EN 2888:2006 plays a critical role in ensuring reliability, safety, and performance in high-stress environments such as aircraft and spacecraft engineering.
Key Topics
Bolt Configuration and Dimensions
EN 2888:2006 specifies bolts with normal hexagonal heads, a normal cylindrical shank with coarse tolerance, and short threaded length, complying with dimensional standards from ISO 3193. Sizes range according to the aerospace series metric dimensions, with detailed measurements and tolerances provided for thread, shank, head, and other bolt features.Material Requirements
The standard mandates the use of corrosion resisting steel, specifically classified under a strength class of 600 MPa. Bolts must be passivated according to EN 2516 to enhance corrosion resistance and surface stability, which is critical for aerospace environments subject to moisture, temperature fluctuations, and chemical exposure.Mechanical Performance
Bolts meet the minimum tensile strength of 600 MPa at ambient conditions, ensuring robust mechanical performance. Their classification extends to maintaining structural integrity up to 425 °C, making them suitable for components exposed to elevated temperatures without degradation of bolt properties.Marking and Designation
Marking practices are clearly defined to facilitate traceability and identification, adhering to EN 2424 for aerospace product marking. The bolts are designated with codes indicating diameter, length, and optional hole types for locking devices such as lockwire or split pins, aiding in correct application and installation.Quality and Inspection
Manufacturer approvals must comply with aerospace quality management system standards detailed in EN 9100. Inspection requirements include microstructure evaluations for discontinuities and tensile strength testing based on strict coefficients. Some tests typical in bolt qualification such as cold rolling or fatigue strength testing are excluded, streamlining certification while maintaining safety.
Applications
EN 2888:2006 bolts are primarily designed for aerospace industry use where performance under corrosive and high-temperature conditions is critical. Common applications include:
Aircraft Structural Assemblies
Used in airframe construction where mechanical reliability and corrosion resistance are essential for flight safety and longevity.Engine and Hot Section Fastening
Suitable for engine components exposed to elevated temperatures up to 425 °C without loss of strength or integrity.Spacecraft and Satellite Hardware
Ensures durable fastening solutions for aerospace hardware exposed to harsh atmospheric and space conditions.Maintenance and Repair Operations
Standardized bolts facilitate consistent replacement and repair across aerospace fleets, simplifying logistics and ensuring compliance with regulatory requirements.
