Mitutoyo Rectangular Steel Gage Block, 0.21 mm

Gage blocks are primary standards critical to quality control in the manufacture of parts. When using only one length repeatedly, the best practice is to purchase a gage block of that length. The gage block is made of steel and comes with a Certificate of Calibration. Choose the desired grade of gage block when ordering. If grade K is selected, this block is provided with a Certificate of Calibration, which certifies that the block was manufactured using Interferometry. The recommended grade for various applications is described below:

• Grade K: These gage blocks are of the highest accuracy and are intended for use within a temperature-controlled inspection room or calibration laboratory. They are designed to be used as masters and are manufactured by absolute measurement using an interferometer.
• Grade 00: These higher accuracy gage blocks are designed to be used in a controlled environment and are mainly used as reference standards for setting high-precision measuring equipment and for calibrating lower grade gage blocks.
• Grade 0: This grade of gage blocks is designed to be used within an inspection area to verify the accuracy of plug and snap gages and for setting electronic measuring devices.
• Grade AS-1: Gage blocks of this grade are designed to be used on the shop floor to set and calibrate fixtures and precision instruments.
• Grade AS-2: These gage blocks are designed to be used with mounting tools and cutters.
