Precision gage blocks are the primary standards vital to dimensional quality control in the manufacture of parts. Mitutoyo offers a complete selection of gage blocks available in a choice of rectangular or square, metric or inch and steel or CERA (ceramic) types.

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 the 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.

Mitutoyo has established a traceability system for measurement products, up to the Metrology Management Center of the National Institute of Advanced Industrial Science and Technology (AIST), and have been certified by the Japanese government as an accredited laboratory.

The Mitutoyo advanced lapping technique, developed for more than a half century by Mitutoyo, achieves the best flatness and surface roughness needed for gage blocks.

CERA blocks, made of ceramic materials with superior surface quality, were developed by Mitutoyo’s ultra-precision machining techniques and solve problems commonly associated with steel gage blocks:

• Corrosion-Resistant - Anti-corrosion treatment is not required when handled normally (i.e. with fingers), resulting in simple maintenance and storage
• No Burrs Caused by Dents - Since the CERA Block is very hard it will not scratch and is highly resistant to burrs. If a burr is formed, it can easily be removed with a ceramic deburring stone (Ceraston)
• Abrasion Resistant - CERA Blocks have 10 times the abrasion resistance of steel gage blocks
• Dimensional Stability - CERA Blocks are free from dimensional change over time
• Marking - Black characters, indicating the nominal length, inscribed by laser, clearly visible against the white surface of block
• High Wringing Force - An even, dense tissue can maintain a strong wringing force
• Closest Expansion Coefficient to Steel - The thermal expansion coefficient of a CERA Block is similar to that of a steel gage block
• Resistance Against Drops - CERA block material is one of the toughest ceramics materials, and is extremely difficult to crack under normal use
