What is a common tool used to check dimensions and tolerances accurately alongside gage blocks?

The use of a height gage is particularly significant when it comes to checking dimensions and tolerances accurately in machining and manufacturing. Height gages are designed to provide precise vertical measurements from a reference surface, making them ideal companions to gage blocks, which are used to establish a baseline measurement. The height gage allows machinists to measure the height of a workpiece or the depth of a cut, and it can be used on a surface plate to ensure the accuracy and repeatability of measurements.

While calipers and micrometers are also essential tools in measuring dimensions, they are more suited for measuring linear distances rather than vertical heights. A dynamometer, on the other hand, is primarily used to measure force, torque, or power rather than dimensions or tolerances. Thus, the height gage stands out as the tool specifically designed for precision height measurement, making it the correct choice in this context.
