Depth Gauges

Mechanical depth measurement tools (sometimes called vernier depth gauges) are useful linear measurement devices used to measure the depth of holes, slots and recesses with accuracy. They can also be used for inspecting jig, fixtures and die work.

Mechanical depth measurement tool applications

Anyone doing construction or remodelling work and in need of accurate measurements of the depth of a slot, hole or recess will find a mechanical depth measurement tool handy. You can also use them to measure and locate centre distances. This would help with coordinating the distances of buttons from the edges of a rectangular workpiece, for example.
