True or False: The number in the fastener identification table on the engineering drawing must match the number on the fastener box.

The statement is false because fasteners may have different identification numbers due to various reasons, including changes in specifications, substitutions permitted by engineering drawings, or varying inventory management systems between manufacturers and suppliers.

In aerospace and other engineering fields, the drawings serve to specify the required characteristics of fasteners, which may not always directly correlate to the numbers on the fastener boxes. Manufacturers may use standardized fasteners that conform to certain specifications, allowing for substitutions or variations, thus the number in the identification table is not always required to match the packaging.

The key takeaway is that while the fastener used must meet the required specifications outlined in the engineering drawing, the identification number itself is not a strict one-to-one match with the number on the fastener box. This flexibility allows mechanics and engineers to apply practical solutions in assembly and maintenance, ensuring safety and performance according to engineering requirements.
