Mitutoyo's Steel Rectangular Thin Gage Block Set Grade AS-1 These gage blocks are intended for shop-floor use to set and calibrate fixtures, as well as precision instruments. Blocks included in set... .005", .010", .015", .020", .025" .030", .035", .040", .045", .050" A Certificate of Calibration traceable to NIST is included with ALL Mitutoyo Gage Block Sets. Mitutoyo gage blocks guarantee such a high accuracy that users can use them with complete confidence. Precision gage blocks are the primary standard vital to dimensional quality control in the manufacture of parts. The lapping technique is one of Mitutoyo's specialties. Their advanced lapping technique, developed for more than a half century, allows them to achieve the best flatness and surface roughness needed for gage blocks, allowing for the wringing of multiple gage blocks together.High-carbon, high-chrome steel is employed to sufficiently satisfy a variety of material characteristics required for gage blocks. A high degree of hardness, obtained through heat treatment technology, as well as methodically repeated heat treatment, have successfully reduced deterioration change over time.
