True or False: If the driven head does not fit into the NoGo end of the gauge, the diameter of the driven head is larger than the minimum allowable diameter and is acceptable.

The assertion that if the driven head does not fit into the NoGo end of the gauge, the diameter of the driven head is larger than the minimum allowable diameter and is acceptable is correct. In quality control and inspection processes, a NoGo gauge is designed to ensure that a specific feature, in this case the diameter of a rivet head, does not exceed a maximum limit.

If the driven head does not fit into the NoGo gauge, it means the diameter is indeed larger than what is permissible according to the specifications. That indicates a potential issue because an oversized head could affect the integrity of the rivet joint and, consequently, the overall structural integrity of the assembly in aerospace applications. Thus, any driven head that does not fit the NoGo end would not be acceptable.

This understanding emphasizes the importance of following the specifications for part dimensions to maintain safety and performance standards in aerospace manufacturing.
