BS EN 2930:1996

Overview

BS EN 2930:1996 specifies the requirements for double hexagon head bolts made from a heat-resisting nickel base alloy, specifically NI-P101HT (Waspaloy). These bolts feature a relieved shank and a long thread, designed to perform under extreme conditions. The classification of these bolts is 1210 MPa at ambient temperature and 730°C, making them suitable for high-stress applications in aircraft and space vehicle engineering.

Key Requirements

The standard outlines the technical specifications and testing methods necessary to ensure the quality and performance of the bolts. Key requirements include:

• Material Composition: The bolts must be manufactured from NI-P101HT (Waspaloy), a nickel-based alloy known for its excellent mechanical properties at elevated temperatures.
• Mechanical Properties: The bolts are classified with a tensile strength of 1210 MPa at ambient temperature, ensuring they can withstand significant loads.
• Temperature Resistance: The bolts maintain their integrity and performance at temperatures up to 730°C, making them ideal for high-temperature environments.
• Surface Treatment: Silver plating is required to enhance corrosion resistance and improve the performance of the bolts in various environments.

Implementation Benefits

Adopting BS EN 2930:1996 for bolt specifications provides several practical benefits:

• Enhanced Reliability: The stringent requirements ensure that the bolts can perform reliably under extreme conditions, reducing the risk of failure in critical applications.
• Improved Safety: Compliance with this standard contributes to the overall safety of aircraft and space vehicles, as high-quality fasteners are essential for structural integrity.
• Streamlined Procurement: Standardisation simplifies the procurement process for manufacturers and suppliers, ensuring that all parties are aligned on specifications and quality expectations.
• Compatibility: The use of a recognised standard facilitates compatibility with other components and systems, promoting interoperability in complex engineering projects.

Compliance Value

Compliance with BS EN 2930:1996 is crucial for manufacturers and engineers in the aerospace sector. Adhering to this standard demonstrates a commitment to quality and safety, which is vital for regulatory approvals and certifications. Furthermore, it helps organisations meet the requirements set forth by aviation authorities, thereby enhancing their reputation in the industry.

In summary, BS EN 2930:1996 provides essential guidelines for the production and use of double hexagon head bolts made from heat-resisting nickel base alloy. By following this standard, organisations can ensure the reliability, safety, and performance of their aerospace components, ultimately contributing to the advancement of aircraft and space vehicle engineering.
