    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.
    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.
    Steel—Steel blocks are the most common choice for gauge blocks.

    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.
    Steel—Steel blocks are the most common choice for gauge blocks.

    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.
    Metric
    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.
    Steel—Steel blocks are the most common choice for gauge blocks.

    Use the Starrett 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 have been laboratory calibrated and include NIST traceable certification with the tested measurements. The blocks are individually numbered for recalibration.
    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 means these gauge blocks are our most accurate. They help verify that precise measuring instruments, such as micrometers and calipers, are taking accurate readings.
    Use a gauge block holder (not included) to create a custom repeatable measurement by stacking multiple blocks together. To prevent your gauge block combinations from wearing down over time, add wear blocks (not included) on each end.

    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.
    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.
    Steel—Steel blocks are the most common choice for gauge blocks.

    Riser Block

    Set the standard for your height gauges. These calibrators combine gauge blocks—a true source of measurement—and a micrometer head for refining the gauge block measurement even more. Since they’re so precise at checking that height gauges take accurate readings, they’re often used in metrology labs. Rather than stacking gauge blocks, line up your height gauge against the built-in blocks. They’re staggered to expose both the top and bottom faces, which lets you check height from either bottom up or top down. To fine-tune the entire stack up and down, twist the micrometer head. No need to calculate anything, since the counter keeps track of adjustments and total height shows on the display.
    These calibrators include a zero-setting block to make sure your measurements start from an exact reference point. They also have zero-position memory to retain the measuring position even when turned off. This is also known as absolute (ABS) positioning. To warn you about issues that could skew readings, such as low battery and calculation errors, they show alerts on the display. An SPC data output lets you connect them to a computer or data processor to analyze data and monitor measurements in real time.
    Riser blocks (sold separately) extend the height range. Precisely manufactured, they have tolerances as tight as our typical gauge blocks of similar sizes. Snap them seamlessly to the bottom of your calibrator with the pins. To add the riser height to your total measurement, input the height into the calibrator’s counter.
