Overview

The BS EN 8.3552 standard outlines the specifications for 100° countersunk screws with a normal head, featuring a Spiral Drive Recess. These screws are designed for use in aerospace applications and are manufactured from heat and corrosion-resistant steel. The standard specifies that the screws should be passivated to enhance their resistance to corrosion, ensuring reliability in demanding environments.

Key Requirements

• Material Specifications: The screws must be made from heat and corrosion-resistant steel, ensuring durability and performance under high temperatures and corrosive conditions.
• Mechanical Properties: The screws are classified with a tensile strength of 1,100 MPa at ambient temperature, making them suitable for high-stress applications.
• Temperature Resistance: The screws can withstand temperatures up to 425 °C, which is critical for aerospace applications where thermal stability is paramount.
• Design Features: The 100° countersunk design allows for flush mounting, reducing aerodynamic drag and enhancing the overall performance of the assembly.

Implementation Benefits

Adopting the BS EN 8.3552 standard for screws in aerospace applications provides several benefits:

• Enhanced Reliability: The use of passivated heat and corrosion-resistant steel ensures that the screws maintain their integrity in harsh environments, reducing the risk of failure.
• Improved Performance: The design and material specifications contribute to the overall performance of aerospace structures, where every component plays a critical role.
• Streamlined Compliance: By adhering to this standard, manufacturers can simplify the compliance process with regulatory bodies, ensuring that their products meet industry requirements.

Compliance Value

Compliance with BS EN 8.3552 is essential for manufacturers and suppliers in the aerospace sector. This standard not only ensures that products meet rigorous safety and performance criteria but also enhances the credibility of the manufacturer in the eyes of clients and regulatory authorities. By using components that conform to this standard, companies can demonstrate their commitment to quality and safety, which is crucial in the highly regulated aerospace industry.

In summary, BS EN 8.3552 provides a comprehensive framework for the design and manufacture of high-performance screws that are critical in aerospace applications. Adhering to this standard helps ensure product reliability, safety, and compliance, ultimately contributing to the success of aerospace projects.
