Measure height more precisely than standard height gauges. These gauges are often used to mark material before cutting it for machining and toolmaking. They have two vertical scales—a main scale and a sliding vernier scale. The vernier scale splits the graduation marks on the main scale into smaller increments for a more accurate reading. Set your initial height, then fine-tune with the adjustment screw.

Reach deep into small holes and slots for precise depth measurements. This gauge has a rod to measures the depth of recesses where the blade won’t fit. The blade has a hook which grabs the edge of an object for easy alignment. Markings are etched for wear resistance.

These Starrett gauges measure height more precisely than standard height gauges. Use them to mark material before cutting it for machining and toolmaking. They have two vertical scales—a main scale and a sliding vernier scale. The vernier scale splits up the graduation marks on the main scale into smaller increments for a more accurate reading. Set your initial height, then fine-tune with the adjustment screw.

All come with a pointed carbide-tipped scriber and a scriber clamp to hold it in place. The pointed tip makes precise, fine lines, but it wears over time.

The durable, analog design of these gauges holds up in machine and toolmaking shops where you regularly need to measure and mark material before cutting. Because they’re analog, they’re best when you don’t need to transfer data. In addition to their dial, they have two mechanical counters that display measurements—one counts up, the other counts down. Twist the hand wheel to adjust the height up and down the column. For repeat marking, set the attached scriber at a specific height. Use the zero-set button to start measuring at any point.

Read measurements on a dial or using the two mechanical analog counters (one counts up; the other counts down). Use the hand wheel to adjust height up and down the column, and set the attached scriber at a specific height for repeat marking.
