What is the second type of gauge used to inspect a driven head besides spoon gauges?

The second type of gauge used to inspect a driven head, alongside spoon gauges, is H-gauges. H-gauges are specifically designed to provide accurate measurement in the inspection process of components, particularly where precise alignment and dimensional accuracy are crucial. They are shaped in such a way that they can measure the features of a driven head effectively, allowing mechanics to ensure that the head is properly fitted and functioning as intended.

This type of gauge is often used in various aerospace applications where adherence to tight tolerances is necessary for safety and functionality. H-gauges facilitate the verification of critical dimensions and can be used in quality control processes to ensure compliance with engineering specifications, which is vital in the aerospace industry.
