Micrometer Inspection Gage Block Sets

The Mitutoyo Micrometer Inspection Gage Block set was designed specifically for micrometer inspection.

Features & Benefits

The Mitutoyo Micrometer Inspection Gage Block set is used to inspect a variety of micrometers with high accuracy. These gage blocks can be stacked for either horizontal or vertical measurements. The Mitutoyo steel gage blocks are constructed of high-carbon, high-chrome steel while our CERA gage blocks are constructed of ceramic materials with superior surface qualities and corrosion resistance. Parallelism can be measured by attaching the optional optical parallel to the gage block set.

  • Available in Metric and Inch block sets
  • Available in steel and CERA sets
  • Optional optical parallel and Micro Checker is available
  • Can be measured in both vertical and horizontal position
  • Innovative lapping techniques give these gage blocks exceptional flatness and ideal surface roughness
  • Specific, repeated heat treatment of steel blocks reduce deterioration change over time
  • CERA blocks are free from dimensional change over time; have 10 times the abrasion resistance of steel gage blocks
  • Black characters on gage blocks are inscribed by laser and clearly visible
  • Provided with Inspection Certificate
  • Supplied in a solid wooden case
