Mitutoyo Gauge Block Sets
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. All blocks include a certificate of compliance to certify their sizes are within tolerance. The certificate also lists when each block will require recalibration.
Put multiple gauge blocks together in a gauge holder (not included) to create a custom repeatable measurement. Add wear blocks (not included) on each end of your gauge block combinations to prevent them from wearing down over time.
Each block has a grade per ASME B89.1.9. Grades are based on tolerance—the smaller the tolerance, the greater the accuracy.
Grade AS-1 gauge blocks have a slightly higher tolerance. They’re the most common grade of gauge block.
Square blocks have a hole that runs through their center. Stack multiple square blocks together and secure them with a rod (not included).
Steel blocks are the most common choice.
