    Confirm your depth micrometer is accurate. These gauges check if your micrometer starts measuring at zero. With six highly accurate reference depth points that range from 1″ to 6″, you can check the accuracy of your depth micrometer and adjust if it comes out of calibration over time. Twist the micrometer's spindle until the tip of the rod is touching the surface of the gauge block and check the reading. Once zeroed, your depth micrometer is ready to measure your parts.

    Inspect micrometer spindle and anvil tips to identify whether they're worn or out of parallel. These discs help you keep your micrometer measuring accurately, especially after repeatedly measuring hard items such as ball bearings. Place them between the anvil and spindle and look at the resulting light pattern on the glass.
    Optical parallels determine if your anvil and spindle are parallel. You’ll know your micrometer is out of parallel if the spindle side reflects a different number of lines than the anvil side. Each parallel includes four discs to check each quarter-turn of your spindle and identify where it has worn down.

    Inspect micrometer spindle and anvil tips to identify whether they're worn or out of parallel. These discs help you keep your micrometer measuring accurately, especially after repeatedly measuring hard items such as ball bearings. Place them between the anvil and spindle and look at the resulting light pattern on the glass.
    Optical flats determine if your anvil is no longer flat. If the lines you see are curved, your anvil is worn.
