Is it important for the identification number on the fastener box to match the number in the fastener identification table on the engineering drawing?

Ensuring that the identification number on the fastener box matches the number in the fastener identification table on the engineering drawing is crucial for a variety of reasons. The fastener identification number is a unique reference that denotes specific characteristics of the fastener, such as its type, material, size, strength, and finish.

When assembling aircraft components, using the correct fasteners is essential for maintaining structural integrity and ensuring safety. If the identification number does not match, it raises concerns about whether the fastener has the appropriate specifications required for that assembly. Utilizing the wrong fastener could lead to failures in assembly, which could have serious implications for the aircraft's performance and safety.

Moreover, following engineering drawings and specifications is vital in the aerospace industry, as it adheres to established standards and regulatory requirements. Verification of fastener identification numbers acts as an additional layer of quality control within the assembly process, helping to prevent errors that could arise during fabrication.

Therefore, matching the identification number on the fastener box with that on the engineering drawing is a fundamental practice in aerospace assembly, reinforcing the importance of precision and reliability in the industry.
