Mitutoyo 611207-531 Steel Gage Block 7 in Grade 0

Product Description

The MITUTOYO 611207-531 is a rectangular steel gage block measuring 7.00000 inches, manufactured to Grade 0 accuracy. Gage blocks are precision-ground reference standards used to establish, verify, or transfer dimensional measurements in metrology, machining, and inspection environments. Grade 0 indicates a high level of dimensional accuracy conforming to ASME standards, making this block suitable for calibration labs, quality control departments, and precision machine shops. Each block ships with a Certificate of Inspection documenting its measured value and conformance to the applicable accuracy grade. Metrology technicians, tool and die makers, and quality inspectors are the primary users of this type of reference standard.

This gage block is used in dimensional inspection setups requiring a traceable 7-inch reference length. Typical applications include setting comparators, verifying part dimensions on surface plates, and calibrating measuring instruments. It is appropriate for both shop-floor inspection and controlled metrology lab environments where ASME-grade reference standards are required. Its rectangular geometry allows for stacking with other gage blocks when wringing sets are assembled for custom reference lengths.

Key Features

• Grade 0 accuracy conforming to ASME standards
• Precision size of 7.00000 inches for traceable dimensional reference
• Steel construction for durability and wear resistance
• Includes Certificate of Inspection for traceability documentation
• Rectangular geometry compatible with standard wringing and stacking techniques

Compatibility

Designed as an OEM-style precision reference standard for use in ASME-compliant dimensional inspection and calibration applications.

Installation Notes

Gage blocks should be handled by metrology technicians or trained quality personnel following established calibration procedures. Store blocks in their protective case when not in use and allow adequate thermal stabilization time before use, as steel expands with temperature changes. Clean contact surfaces with an appropriate gage block cleaning solution before wringing or measurement. Do not drop, stack without proper wringing technique, or store in high-humidity environments that could cause corrosion.
