What are the three common sizes of safety wire?

The three common sizes of safety wire are .020, .032, and .040. These sizes are standardized for use in aviation and other fields to ensure that components are secured properly to prevent them from loosening due to vibration or other forces.

The .020 safety wire is typically used for smaller fasteners or lighter applications, while .032 is a versatile size used for a variety of fasteners in aviation. The .040 size is generally reserved for larger fasteners that require a stronger hold. Using the appropriate size is crucial for ensuring the integrity of the fastening system, contributing to the overall safety and reliability of aircraft systems.

In comparison, other options do not reflect the standard sizes commonly recognized and utilized in aviation maintenance practices, making them less applicable for typical situations involving safety wire.
