What instrument is used to measure gage pin height?

The height gage is an instrument specifically designed for measuring vertical dimensions with precision. It typically features a fine-tuning adjustment to allow for accurate height measurements, which is ideal for measuring the height of gage pins. The height gage can also be used in conjunction with a surface plate to provide a stable reference point, ensuring that the measurements taken are both repeatable and reliable.

Calipers, while useful for measuring a variety of dimensions, do not provide the level of precision required for gage pin height measurement in a vertical context. Micrometers, although precise, are generally better suited for measuring small diameters or thickness rather than height. Dial indicators are primarily used for measuring small displacements or variations in height, but they do not provide the same straightforward measurement capacity as height gages for setting or checking gage pins specifically.
