What part of the Hi-Lok is inspected for height alignment with Go/NoGo gauges?

The pin of the Hi-Lok is the part that is inspected for height alignment using Go/No-Go gauges. This measurement is crucial because the pin must fit within specific tolerances to ensure that it can be properly installed and function effectively when securing components together. The Go/No-Go gauge will provide a quick assessment of whether the pin meets the necessary height specifications, thus confirming its suitability for use in assembly.

If the pin is out of alignment, it can lead to assembly issues, such as improper fastening or structural integrity concerns in the overall assembly. Therefore, this inspection ensures that the pin can ensure the reliability and safety of the aircraft assembly. Other components may require different forms of inspection, but height alignment specifically pertains to the pin in this context.
