Mitutoyo 613191-531 Ceramic Rectangular Individual Gage Block 0.100 In ASME Grade 0

The Mitutoyo 613191-531 is a 0.100-inch individual rectangular ceramic (CERA) gage block conforming to ASME B89.1.9-2002 Grade 0 standards. Part of Mitutoyo's Series 516 lineup, this precision instrument is an essential reference standard for dimensional quality control, calibration, and metrology applications in workshop and inspection environments.

Gage blocks — also known as gauge blocks, Jo blocks, slip gages, or Johansson gages — are used to calibrate measuring equipment and standardize length measurement in manufacturing industries. This block can be used independently or wrung together with other blocks to build up a precise composite length for a given measurement task.

Key Features:

• ASME Grade 0 Certified: Supplied with a Mitutoyo inspection certificate verifying compliance with ASME B89.1.9-2002 standards for flatness, length, parallelism, and surface finish
• NIST-Traceable: Inspection certificate specifies the deviation of the block from its nominal 0.100-inch length for full traceability
• Ceramic (CERA) Construction: White ceramic material developed using Mitutoyo's ultra-precision machining techniques, providing superior dimensional stability and resistance to thermal expansion compared to steel blocks
• Rectangular Base: Rectangular profile ensures accurate and reliable wringing to other gage blocks or reference surfaces
• Etched Identification Number: Unique ID number etched directly into the block for individual traceability and record-keeping
• Nominal Length: 0.100 inches (inch measurement engraved on block)

This Grade 0 ceramic gage block is well-suited for use in inspection areas to verify the accuracy of plug gages, snap gages, electronic measuring devices, and other precision instruments. Its ceramic construction offers excellent wear resistance and corrosion resistance, making it a long-lasting alternative to traditional steel gage blocks.
