BS EN 2863:2010

Overview

BS EN 2863:2010 specifies the requirements for self-locking anchor nuts designed for use in aerospace applications. These nuts are engineered to perform effectively at high temperatures, specifically up to 315°C, while maintaining a classification strength of 1100 MPa at ambient temperature. The standard applies to nuts with a 90° corner and a counterbore, manufactured from heat-resisting steel and lubricated with MoS2 (molybdenum disulfide).

Key Requirements

• Material Specification: The nuts must be constructed from heat-resisting steel that meets the specified mechanical properties.
• Temperature Resistance: The design must ensure functionality at elevated temperatures, specifically up to 315°C.
• Self-Locking Mechanism: The nuts must incorporate a self-locking feature to prevent loosening under dynamic loads.
• Counterbore Design: The counterbore feature is crucial for proper fit and function in aerospace assemblies.
• MoS2 Lubrication: The application of MoS2 lubrication is essential for reducing friction and wear during installation and operation.

Implementation Benefits

Adhering to BS EN 2863:2010 provides several practical benefits for aerospace manufacturers and compliance professionals:

• Enhanced Safety: The self-locking design significantly reduces the risk of component failure due to loosening, which is critical in aerospace applications.
• Improved Performance: The heat-resisting properties of the materials ensure that the nuts maintain their integrity and performance under extreme conditions.
• Streamlined Assembly: The counterbore design facilitates easier installation and ensures a secure fit within assemblies, reducing assembly time and costs.
• Reduced Maintenance: The use of MoS2 lubrication minimizes wear and tear, leading to lower maintenance requirements over the lifespan of the components.

Compliance Value

Compliance with BS EN 2863:2010 not only ensures that aerospace components meet industry standards but also enhances the credibility of manufacturers in the global market. By adhering to this standard, organisations can:

• Meet Regulatory Requirements: Compliance with recognised standards is often a prerequisite for certification in the aerospace industry.
• Enhance Product Quality: Following the specifications outlined in the standard leads to improved product quality and reliability.
• Facilitate International Trade: Compliance with European standards can simplify the process of entering international markets, as many countries recognise these standards.

In conclusion, BS EN 2863:2010 is a critical standard for the aerospace industry, providing essential guidelines for the design and manufacture of self-locking anchor nuts. By implementing these specifications, manufacturers can ensure safety, performance, and compliance in their aerospace applications.
