BS EN 2884:1996

Overview

BS EN 2884:1996 specifies the requirements for pan head screws with an offset cruciform recess, designed for use in aircraft and space vehicle engineering. These screws are manufactured from titanium alloy and feature a coarse tolerance normal shank with a short thread. The anodized MoS2 lubrication enhances performance in demanding environments. The classification of these screws is 1100 MPa at ambient temperature and 315°C, making them suitable for high-stress applications.

Key Requirements

The standard outlines several critical specifications that must be adhered to during the manufacturing process:

• Material: Titanium alloy, known for its high strength-to-weight ratio and corrosion resistance.
• Head Type: Pan head with an offset cruciform recess, facilitating easy installation and removal.
• Tolerance: Coarse tolerance normal shank ensures compatibility with various components.
• Thread Length: Short thread design optimizes performance in tight spaces.
• Lubrication: Anodized MoS2 lubrication reduces friction, enhancing durability and performance.
• Temperature Classification: Capable of withstanding up to 315°C, suitable for high-temperature applications.

Implementation Benefits

Utilising BS EN 2884:1996 compliant screws offers several advantages in aerospace applications:

• Enhanced Performance: The titanium alloy construction ensures that screws maintain structural integrity under extreme conditions.
• Weight Reduction: The lightweight nature of titanium contributes to overall weight savings in aircraft and space vehicles.
• Improved Assembly Efficiency: The design features facilitate quick installation, reducing assembly time and costs.
• Corrosion Resistance: The anodized finish protects against environmental degradation, extending the service life of components.

Compliance Value

Adhering to BS EN 2884:1996 ensures compliance with international standards for aerospace components. This compliance is crucial for manufacturers and operators in the aerospace sector, as it:

• Meets Regulatory Requirements: Compliance with this standard helps satisfy the stringent regulations set forth by aviation authorities.
• Enhances Safety: Using certified components reduces the risk of failure, contributing to overall safety in aircraft and spacecraft operations.
• Facilitates Quality Assurance: Implementing the standard promotes consistent quality in manufacturing processes, leading to reliable performance.
• Supports Global Trade: Compliance with recognised standards simplifies international transactions and partnerships in the aerospace sector.

In conclusion, BS EN 2884:1996 provides essential guidelines for the production of high-performance screws in the aerospace industry. By adhering to these standards, manufacturers can ensure product reliability, safety, and compliance with regulatory requirements.
