Mitutoyo 613192-521 Ceramic Gage Block 0.2 in Grade 00

Product Description

The MITUTOYO 613192-521 is a rectangular ceramic gage block measuring 0.2 inches nominal length, manufactured to Grade 00 accuracy. Gage blocks are precision-ground reference standards used to establish and verify dimensional measurements in calibration labs, machine shops, and quality control environments. Grade 00 is the highest accuracy classification under ASME standards, making this block appropriate for master-level calibration work where the tightest tolerances are required. Ceramic construction delivers high hardness, low thermal expansion, and strong resistance to wear and corrosion compared to steel alternatives. Metrologists, calibration technicians, and precision machinists are the primary users.

This block is suited for use in dimensional calibration laboratories, tool rooms, and inspection departments requiring traceable length standards. It functions as a stand-alone reference block or as part of a gage block set for selective wringing to build up a target dimension. Applications include calibrating micrometers, vernier calipers, height gages, and CMM reference standards. Both industrial and metrology-lab environments benefit from the stability and longevity of the ceramic material at this grade level.

Key Features

• Grade 00 accuracy classification per ASME standards — highest precision grade for master calibration use
• Ceramic material provides superior hardness and wear resistance compared to steel gage blocks
• Low thermal expansion coefficient helps maintain dimensional stability across typical lab temperature variations
• 0.20000-inch nominal length with five-decimal precision designation
• Wringing-compatible flat-lapped surfaces for selective stack assembly

Compatibility

Designed as an individual replacement or supplemental ceramic gage block conforming to ASME standards, suitable for use alongside any ASME-compliant gage block set of matching grade and material type.

Installation Notes

Gage blocks are handled by metrology and calibration technicians in controlled environments. Clean measuring surfaces thoroughly with lint-free cloth and appropriate solvent before wringing to prevent scoring. Store blocks flat on a clean surface or in a protective case when not in use to avoid edge chipping of the ceramic material. Avoid dropping or impacting ceramic blocks, as ceramic is more brittle than steel and is susceptible to fracture under shock loads.
