Mitutoyo 611142-131 / .102" Steel Gauge Block, Grade 1

Mitutoyo, at its factory at Miyazaki in Japan, has a long tradition in the manufacture of gauge blocks. Two materials are used, alloy steel and ceramic, both providing outstanding quality and durability. Steel is the orignal, and still the most popular material used in the manufacture of gauge blocks. Steel blocks are the most economical choice and have a long working life if used and maintained carefully. Ceramic blocks are the natural choice where extreme wear resistance and easy maintenance are the principal requirements.

• Made of high quality alloy steel, carefully heat treated and stress relieved for high stability and precision lapped for good wringing properties. Slightly rounded edges.


• Each gauge block is marked with an identification number. Gauge block hardness is 800 HV (64 HRC) for high wear resistance.


• Mitutoyo gauge blocks are graded according to national or international standards during manufacture under the most stringent quality control procedures. Every block is well within the accuracy limits of the tolerance grade assigned.


• Tolerance Grade 1: For calibrating and setting test gauges, reference gauges, and for adjusting length measuring instruments as well as for accurate testing in quality control.
