BS EN 2264:1996

Overview

BS EN 2264:1996 specifies the requirements for self-locking anchor nuts designed for use in aircraft and space vehicle engineering. These nuts are characterised by their floating design, two lug configuration, and incremental counterbore. Manufactured from alloy steel, they are cadmium plated and lubricated with MoS2, ensuring optimal performance in demanding environments.

Key Requirements

The standard outlines critical specifications that must be adhered to for compliance, including:

• Material: Alloy steel with cadmium plating
• Lubrication: MoS2 for enhanced friction reduction
• Load Classification: 900 MPa at ambient temperature
• Temperature Resistance: Up to 235°C

These specifications ensure that the nuts can withstand the rigorous conditions typical in aerospace applications, including high stress and temperature variations.

Implementation Benefits

Utilising BS EN 2264:1996 compliant nuts provides several advantages in aircraft and space vehicle engineering:

• Reliability: The self-locking feature prevents loosening under vibration, a common issue in aerospace environments.
• Durability: Cadmium plating and MoS2 lubrication enhance corrosion resistance and extend the life of the component.
• Performance: The design allows for precise load distribution, which is crucial for maintaining structural integrity.
• Standardisation: Compliance with this standard facilitates interoperability and compatibility with other aerospace components.

Incorporating these nuts into engineering designs can significantly improve the safety and performance of aircraft and space vehicles.

Compliance Value

Adhering to BS EN 2264:1996 is essential for compliance with regulatory requirements in the aerospace sector. This standard not only ensures that components meet stringent safety and performance criteria but also supports manufacturers in achieving certification from relevant aviation authorities.

By implementing the guidelines set forth in this standard, organisations can mitigate risks associated with component failure, thereby enhancing overall operational safety. Furthermore, compliance can lead to improved marketability and trust among stakeholders, including regulatory bodies and customers.

In summary, BS EN 2264:1996 provides a robust framework for the use of self-locking anchor nuts in aerospace applications, ensuring reliability, durability, and compliance with industry standards.
