    Gauge Blocks

    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. All blocks include a certificate of compliance to certify their sizes are within tolerance. The certificate also lists when each block will require recalibration.
    Each block has a grade per ASME B89.1.9. Grades are based on tolerance—the smaller the tolerance, the greater the accuracy.
    Use a gauge block holder (not included) to create a custom repeatable measurement by stacking multiple blocks together.
    Square—Square blocks have a hole that runs through their center. Stack multiple square blocks together and secure them with a rod (not included).
    Grade 0 Gauge Block—Grade 0 gauge blocks are our most accurate. They help verify that precise measuring instruments, such as micrometers and calipers, are taking accurate readings.
    Grade AS-1 Gauge Block—Grade AS-1 gauge blocks have a slightly higher tolerance. They’re the most common grade of gauge block.
    Ceramic—Ceramic blocks are more resistant to wear and corrosion than steel blocks. They won’t expand or contract as temperatures change. Use them in cleanrooms—they’re nonmagnetic so they won’t pick up any iron or dust.

    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 come with a certificate traceable to NIST to certify they were calibrated in a lab and meet tight tolerances. The blocks are individually numbered for 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 to prevent your gauge block combinations 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 0 Gauge Block—Grade 0 gauge blocks are our most accurate. They help verify that precise measuring instruments, such as micrometers and calipers, are taking accurate readings.
    Grade AS-1 Gauge Block—Grade AS-1 gauge blocks have a slightly higher tolerance. They’re the most common grade of gauge block.
    Ceramic—Ceramic blocks are more resistant to wear and corrosion than steel blocks. They won’t expand or contract as temperatures change. Use them in cleanrooms—they’re nonmagnetic so they won’t pick up any iron or dust.
