Dimensional gages and instruments provide quantitative measurements of product or component dimensional and form attributes such as wall thickness, depth, height, length, inner diameter (ID), outer diameter (OD), taper or bore

Bore and ID gages are designed for internal diameter dimensional measurement or assessment

Form gages and form gaging systems are used to inspect parameters such as roundness, angularity, squareness, straightness, flatness, runout, taper and concentricity.

Plug and pin gauges are used to compare hole and slot dimensions or locations to specific tolerances.

Air gages use pneumatic pressure and flow to measure or sort dimensional attributes

Inspection, layout and gaging accessories include probes, sensors, hand tools, styli, contact tips, supplies and other components for dimensional measurement, inspecting, marking, layout or other manufacturing or machine shop applications

Micrometers are instruments for precision dimensional gaging consisting of a ground spindle and anvil mounted in a C-shaped steel frame.
