True or False: The Go pin of a Go/NoGo gauge should fit completely through an assembly if the hole has been drilled to size properly.

The statement is true because a Go/NoGo gauge is a precision tool used in machining and manufacturing to ensure that a drilled hole meets specified dimensional tolerances. The Go pin of the gauge is designed to fit into the hole if it has been drilled correctly to the specified size. This confirms that the hole is within the acceptable limits for diameter and that the manufacturing process has been executed properly. If the Go pin fits completely through the assembly, it indicates that the hole is the correct size. Conversely, if the Go pin does not fit, it signifies that the hole is either too small or improperly drilled, thus failing the inspection. This function is crucial for quality control in aerospace manufacturing, where precise dimensions are critical for part compatibility and safety.

The other options introduce possibilities that deviate from the fundamental purpose of the Go/NoGo gauge, such as varying based on the material or gauge type, which can lead to misunderstandings about its intended use in measurement and inspection processes.
