The calibrated Mitutoyo 516-931-26CAL gage block set is for use with the Mitutoyo Micro Checker (sold separately) to inspect micrometers. This set has a measurement range of 0.0625" to 2.0". The nine rectangular blocks come in lengths of 0.0625", 0.100", 0.125", 0.200", 0.250", 0.300", 0.500", 1", and 2", and are constructed of high-carbon, high-chrome steel for durability and to minimize length changes. This set also comes with an optical parallel that is 0.5" thick for measuring flatness and parallelism of the measuring faces of the micrometers being inspected. This set meets the American Society of Mechanical Engineers (ASME) B89.1.9 standards for grade AS-1 for dimensions and parallelism. Mitutoyo calibrated tools include a Certificate of Calibration that provides evidence that the tool has been calibrated and is within allowable error specifications. Mitutoyo calibrated tools are certified by Mitutoyo's American Association for Laboratory Accreditation-accredited calibration laboratory (A2LA Certificate #750-01) to the International Organization for Standardization/International Electrotechnical Commission (ISO/IEC) 17025 International Standard for testing and calibration laboratories.
The set comes in a fitted wooden case.

Gage blocks (also called gauge blocks, Jo blocks, Hoke blocks, and Johansson gauges) are precision ground and lapped metal or ceramic blocks, used for calibrating precision measuring equipment and as a length standard in manufacturing. Gage blocks are square or rectangular in shape, with flat and parallel measuring surfaces, and usually have an engraved unique serial number and nominal length (provided in either inches or millimeters). They often come in sets with blocks of varying lengths, so that many different standard lengths can be created by stacking and wringing them. Wringing is the process of sliding blocks together with a small amount of pressure, in order to create a longer gage block stack.
Mitutoyo manufactures precision measuring tools, metrology equipment, and related systems. The company, founded in Tokyo in 1934, formed Mitutoyo America Corporation in 1963 with headquarters in Aurora, IL.
