Individual Gage Blocks are precision measurement tools used to calibrate and verify the accuracy of other measuring instruments. They are rectangular, metal blocks made of high-grade steel or ceramic materials, with two or more extremely flat and parallel surfaces.

Unlike gage block sets, Individual Gage Blocks are sold as single blocks with a specific dimension. They are available in various sizes, ranging from 0.1mm to several inches, and are typically used as a replacement block for an existing set or for a custom measurement application.

Individual Gage Blocks are usually calibrated to an accuracy of 0.00005 inches (0.00127mm) or better, and they come in various grades, with Grade 0 being the most accurate, followed by Grade AA, Grade A, and Grade B. The blocks are usually etched or stamped with their nominal dimension and grade for easy identification.

These blocks are used for fine-tuning the accuracy of micrometers, calipers, dial indicators, and other measuring instruments that require high levels of precision. They are also used for setting up and checking the accuracy of machine tools, such as lathes and milling machines, and for other precision measurement applications in industries like aerospace, automotive, and engineering.

Overall, Individual Gage Blocks are essential tools for maintaining the accuracy and precision of measuring instruments and for ensuring the quality of machined parts and components. Their high accuracy, reliability, and durability make them a preferred choice for professionals in various industries who demand the highest levels of precision in their work.
