Overview
SIST EN 4497:2006 is a European standard developed by CEN for aerospace hardware, specifically outlining the characteristics of pan head screws with an offset cruciform recess. These screws feature a close tolerance normal shank and a short thread design, manufactured from titanium alloy, anodized, and finished with an aluminium pigmented coating. The standard sets out the requirements for strength (1 100 MPa at ambient temperature) and temperature resistance (up to 315 °C), ensuring high reliability and performance for aerospace applications.
This standard serves as a crucial specification for manufacturers, suppliers, and users of aerospace fasteners, promoting quality, safety, and interchangeability in demanding environments.
Key Topics
Product Characteristics
- Pan head with offset cruciform recess for enhanced driveability.
- Close tolerance normal shank for precise fit and reduced play.
- Short thread configuration.
- Manufactured from high-strength titanium alloy.
- Surface treatments: anodized with an aluminium pigmented coating for corrosion protection and elevated temperature stability.
- Identification and marking requirements for traceability.
Performance Classification
- Minimum tensile strength: 1 100 MPa at ambient temperature.
- Maximum operating temperature: 315 °C (as determined by the coating).
Dimensional and Tolerance Requirements
- Conformance to referenced ISO and EN standards governing dimensions, tolerances of form and position, and thread profiles.
- Specifications for mass, configuration, and optional features such as hole types and drive configurations.
Applications
SIST EN 4497:2006 is essential within the aerospace sector where high-performance fasteners are required. Practical applications of this standard include:
- Aircraft Structural Assemblies
Used in joining critical aircraft structures where strength, precision, and reliability are paramount. - Engine Components
Suitable for engine areas subjected to elevated temperatures and corrosive conditions. - Spacecraft and Satellites
Ideal for mechanisms exposed to extreme environments, offering lightweight and high strength. - Defense and Military Aircraft
Applied wherever close tolerance, durable fasteners are needed for mission-critical assemblies.
The specification supports consistent procurement, maintenance, and quality control across aerospace projects, minimizing the risk of fastener-related failures.
