Mitutoyo 614223-531 Square Steel Gage Block 12 in Grade 0

Product Description

The MITUTOYO 614223-531 is a square steel gage block manufactured to Grade 0 accuracy and used as a precision dimensional reference in metrology, calibration, and inspection applications. Grade 0 classification indicates tightly controlled dimensional tolerances, making this block suitable for high-accuracy measurement tasks in toolrooms, metrology labs, and quality control environments. The block includes a Certificate of Inspection, confirming it meets stated accuracy requirements at the time of manufacture. Machinists, metrologists, and quality technicians typically work with this type of tooling.

This gage block is intended for use as a precision reference standard in dimensional inspection, gauge calibration, and setup verification tasks. Its square form factor and Grade 0 rating make it appropriate for both bench-top metrology and machine-side setup applications in manufacturing and quality assurance environments. The included Certificate of Inspection supports compliance documentation for facilities operating under quality management standards such as ISO 9001 or AS9100.

Key Features

• Grade 0 accuracy classification per ASME standards for tight dimensional tolerances
• Steel construction for durability and dimensional stability
• Square geometry for versatile reference and setup use
• Includes Certificate of Inspection for traceability documentation
• Nominal size of 12 inches for large-range dimensional reference
• Meets ASME standards for gage block performance

Compatibility

Designed as a precision dimensional reference standard for use in metrology labs, toolrooms, and quality control stations requiring Grade 0 accuracy gage blocks.

Installation Notes

Gage blocks are handled and used by metrology technicians and quality control professionals. Before use, clean contact surfaces with an appropriate gage block cleaning solution to remove oils and particulates that can affect accuracy. Store in the provided case when not in use to prevent surface damage and corrosion. Do not wring or stack dissimilar-grade blocks in a way that risks surface damage to the reference faces.
