What type of gauges are typically used to inspect a driven head?

Spoon gauges and H-gauges are specifically designed for the purpose of inspecting driven heads, particularly in assembly and maintenance applications in the aerospace industry. These gauges help ensure that the driven head is conformed to specific tolerances vital for the proper functioning of components.

Spoon gauges are shaped in a way that allows for measurement of the contour and fit of parts, which is crucial when verifying if a driven head meets the required specifications. Meanwhile, H-gauges are primarily used for checking the height and alignment of fasteners after installation, which is essential for the integrity of assemblies in aircraft structures.

While digital gauges and manual gauges are commonly utilized for a variety of measurement tasks, they do not offer the specialized design needed for the specific inspection tasks associated with driven heads. Similarly, while micrometers and calipers are fundamental tools in precision measurement, they do not specifically address the unique requirements for inspecting driven heads in the same way that spoon and H-gauges do. Thus, the distinct design and intended application of spoon and H-gauges make them the appropriate choice for this type of inspection.
