BS EN 2653:1997

Overview

BS EN 2653:1997 specifies the requirements for screws with a 100° countersunk normal head, slotted, and threaded to the head, manufactured from corrosion-resisting steel and passivated. This standard is crucial for applications in aircraft and space vehicle engineering, ensuring that components meet stringent performance and safety criteria.

Key Requirements

• Material Specification: The screws must be made from corrosion-resisting steel, which provides enhanced durability and resistance to environmental factors.
• Mechanical Properties: The screws are classified to withstand a tensile strength of 600 MPa at ambient temperature and maintain performance at elevated temperatures up to 425°C.
• Design Features: The 100° countersunk head design allows for flush installation, reducing aerodynamic drag and improving the overall aesthetic of the assembly.
• Threading: The screws are threaded to the head, ensuring secure fastening and load distribution in critical applications.

Implementation Benefits

Utilising screws that comply with BS EN 2653:1997 provides several practical benefits:

• Enhanced Safety: Adhering to this standard ensures that the screws will perform reliably under the demanding conditions typical in aerospace applications.
• Quality Assurance: Compliance with BS EN 2653:1997 signifies that the screws have undergone rigorous testing and meet established quality benchmarks.
• Interchangeability: Standardisation allows for easier replacement and maintenance of components across different aircraft and spacecraft, reducing downtime and costs.

Compliance Value

Compliance with BS EN 2653:1997 is essential for manufacturers and engineers in the aerospace sector. It not only ensures that components meet regulatory requirements but also enhances the overall integrity of the engineering process. By following this standard, organisations can:

• Minimise Risk: Reducing the likelihood of component failure through adherence to established specifications.
• Facilitate Audits: Compliance simplifies the audit process, demonstrating a commitment to quality and safety standards.
• Enhance Reputation: Companies that consistently meet or exceed standards gain trust from clients and stakeholders, reinforcing their position in the market.

In conclusion, BS EN 2653:1997 is a vital standard for screws used in aircraft and space vehicle engineering. Its specifications ensure that components are reliable, safe, and of high quality, ultimately contributing to the success and safety of aerospace projects.
