BS EN 2928:1996

Overview

BS EN 2928:1996 specifies the requirements for double hexagon head bolts with a relieved shank and long thread, manufactured from heat-resisting nickel base alloy NI-P100HT (Inconel 718) and silver plated. These bolts are designed for use in aircraft and space vehicle engineering applications where high strength and resistance to elevated temperatures are critical.

Key Requirements

• Material Specification: The bolts are made from Inconel 718, a nickel-chromium alloy known for its excellent mechanical properties and resistance to oxidation and corrosion at high temperatures.
• Mechanical Properties: The bolts are classified with a tensile strength of 1275 MPa at ambient temperature and can withstand temperatures up to 650°C.
• Design Features: The double hexagon head allows for improved torque application and ease of installation, while the relieved shank reduces stress concentrations.
• Surface Treatment: The silver plating provides additional protection against corrosion and enhances the bolt's performance in harsh environments.

Implementation Benefits

Utilising BS EN 2928:1996 compliant bolts in aerospace applications ensures that components can withstand the demanding conditions encountered in flight and space operations. The high strength and temperature resistance of Inconel 718 make these bolts suitable for critical applications where failure is not an option.

Incorporating these bolts into your engineering processes can lead to:

• Enhanced Reliability: The robust material properties ensure that components maintain integrity under stress and high temperatures.
• Improved Safety: Compliance with this standard mitigates risks associated with component failure, contributing to overall safety in aircraft and space vehicle operations.
• Streamlined Procurement: Adherence to recognised standards simplifies the sourcing of materials and components, ensuring consistency and quality across projects.

Compliance Value

Compliance with BS EN 2928:1996 not only meets regulatory requirements but also demonstrates a commitment to quality and safety in engineering practices. This standard is recognised across the aerospace industry, facilitating international trade and collaboration.

By adhering to this standard, organisations can achieve:

• Regulatory Compliance: Meeting industry standards is essential for certification and operational approval from aviation authorities.
• Quality Assurance: Implementing these specifications supports a quality management system that enhances product reliability and performance.
• Market Competitiveness: Compliance with recognised standards can improve marketability and customer trust, positioning your organisation as a leader in aerospace engineering.

In conclusion, BS EN 2928:1996 provides essential guidelines for the specification and application of high-performance bolts in aerospace engineering. By following these standards, organisations can ensure the safety, reliability, and efficiency of their aerospace components.
