Mitutoyo 613191-521 Ceramic Gage Block 0.1 in Grade 00

Product Description

The MITUTOYO 613191-521 is a rectangular ceramic gage block measuring 0.1 inches in length, manufactured to Grade 00 accuracy standards per ASME specifications. Gage blocks of this grade represent the highest tier of dimensional accuracy available and serve as primary reference standards in precision measurement environments. The ceramic construction provides excellent hardness, wear resistance, and dimensional stability compared to steel alternatives. This block is used by metrologists, quality control technicians, and toolroom professionals to calibrate measuring instruments, verify part dimensions, and establish reference datums.

This gage block is suited for use in calibration laboratories, quality assurance departments, and precision manufacturing environments where tight dimensional tolerances must be verified or maintained. Grade 00 blocks are typically reserved for laboratory reference and master-set applications rather than shop-floor use. The 0.1-inch size makes it a standard increment block within a complete gage block set used to build up a wide range of measurement values through wringing.

Key Features

• Grade 00 accuracy rating per ASME standards — highest available accuracy grade for reference-level metrology
• Ceramic material construction provides superior wear resistance and corrosion resistance compared to steel
• 0.10000-inch nominal size (5-decimal precision) for high-confidence dimensional reference
• Rectangular form factor compatible with standard gage block accessories such as holders and jaws
• Suitable for wringing with other gage blocks to build composite measurement values

Compatibility

Designed as an OEM-style rectangular ceramic gage block for use in standard gage block sets and calibration applications conforming to ASME specifications.

Installation Notes

Gage blocks should be handled by metrology or quality control personnel trained in precision measurement practices. Always clean contact faces with an appropriate gage block cleaning solution before wringing or storage to prevent corrosion and contamination. Store blocks in their protective case away from temperature extremes and vibration to preserve dimensional stability. Do not drop or slide blocks across abrasive surfaces, as ceramic material, while hard, can chip under impact.
