A true source of measurement, use these gauge blocks to calibrate measuring equipment, mark precise layouts, or position your fixture or machine components just right.

Use the Mitutoyo gauge blocks in these sets individually or together to take precise measurements or calibrate your measuring tools. They are often used to mark layouts, align machine components, and check that parts are within tolerance.

Use the Starrett gauge blocks in these sets individually or together to take precise measurements or calibrate your measuring tools. All have been laboratory calibrated and include NIST traceable certification with the tested measurements.

Check the position of tools in your CNC machine with the highest degree of precision.
