Transfer precise height measurements from gauge blocks, finished parts, or existing setups to workpieces and new machinery. Often used in toolmaking and other manufacturing processes, these gauges help you check whether parts are uniform and machine settings are consistent. Their rigid, rectangular column makes them less sensitive to vibration than standard height gauges, so your setting won’t shift when you move the gauge. Fine adjustments are made with a hand wheel on the base, rather than on the column, which helps keep the rod steady for the most accurate measurements.

Slide the rod up or down the column to line it up with the object you want to measure, then fine-tune its position with the hand wheel. Lock it in place with a thumb screw before moving the gauge. The rod is removable, so you can also use these gauges with a variance indicator.
