True or False: If the driven head fits into the Go hole in the gauge, the driven head is smaller than the maximum allowable diameter and is acceptable.

The statement is true because when a driven head fits into the Go hole of a gauge, it indicates that the driven head is within the acceptable size range as specified by the engineering standards. The Go gauge represents the maximum allowable size; if a component passes through this gauge, it means the component is smaller than the maximum allowable diameter and thus acceptable for use.

This principle is essential in aerospace assembly as it helps ensure that components fit and function as intended within their designed tolerances. Understanding the function of Go and No-Go gauges is crucial for maintaining quality control in manufacturing processes.
