Mitutoyo Steel Rectangular Micrometer Inspection Gage Block Set with Optical Parallel, ASME Grade 0, 0.0625-2.0" Length (9 Blocks)

The Mitutoyo 516-series Grade 0 Steel Rectangular Inch Micrometer Inspection Gage Block Set includes a set of rectangular-shaped, high-carbon, high-chrome steel gage blocks with nominal length engraved in inches on each, and is supplied with a Mitutoyo inspection certificate that states that the blocks meet American Society of Mechanical Engineers (ASME) B89.1.9-2002 grade 0 standard for flatness, length, parallelism, and surface finish. The inspection certificate specifies the deviation of each individual block from its nominal length. Gage blocks are commonly used to calibrate fixtures and precision instruments in workshop, inspection, and dimensional metrology applications, to inspect tools such as mounting tools, cutters, fixtures, and mechanical parts, and in the gage manufacturing process itself. Micrometer inspection gage blocks are sized for use with a Mitutoyo Micro Checker (sold separately). Grade 0 gage blocks are commonly used in workshop and inspection applications to calibrate and inspect mechanical parts and tools, to verify the accuracy of plug and snap gages, and to set electronic measuring devices. High-carbon, high-chrome steel has a high hardness for minimum deterioration, and is selected for its wear-resistance. Rectangular-shaped blocks provide accurate wringing. The nominal length of each block is measured in inches, and is indicated with laser-etched, black characters. The length of a gage block is usually slightly shorter than its stamped nominal length, to account for the thin layer of oil or wring film used when two or more blocks are wrung together. An identification number is laser-etched on each block for traceability. The set comes with a fitted wooden case for storage. The set includes a Mitutoyo inspection certificate [National Institute of Standards in Engineering (NIST)-traceable] that the blocks meets ASME B89.1.9-2002 standard for flatness, length, parallelism, and surface finish.
