Mitutoyo 613191-521 Rectangular Ceramic Gage Block 0.100 In ASME Grade 00

The Mitutoyo 613191-521 is a 0.100-inch individual rectangular ceramic (CERA) gage block manufactured to ASME Grade 00 — the highest accuracy classification available. Precision gage blocks are the primary dimensional reference standards used in manufacturing quality control, calibration labs, and inspection environments.

CERA Ceramic Construction:

• Zirconia ceramic material provides superior dimensional stability compared to steel, with excellent resistance to thermal expansion and temperature fluctuations
• Exceptional hardness delivers outstanding wear and abrasion resistance for long service life
• Superior surface quality achieved through Mitutoyo's ultra-precision machining techniques
• CERA blocks wring easily with steel blocks as well as with other CERA blocks, ensuring versatile stackability

Precision and Traceability:

• Meets or exceeds all ASME Grade 00 specifications for flatness, parallelism, and surface finish
• Identification number etched directly into the block for full traceability
• Supplied with a Certificate of Inspection with a serial number for documentation and quality records

Rectangular Form Factor:

• Rectangular base geometry enables accurate wringing when stacking blocks to build up precise measurements
• Ideal for tool and cutter positioning, sine bar angle measurement, taper measurement with rollers, and inspection of depth micrometers
• Used to verify the accuracy of plug gages, snap gages, and electronic measuring devices

This individual block is part of Mitutoyo's comprehensive Series 613 CERA gage block line, available in a full range of inch sizes. It is an essential reference standard for quality control, metrology labs, and precision manufacturing inspection.
