Mitutoyo 611141-531 Steel Gage Block 0.101 in Grade 0

Product Description

The MITUTOYO 611141-531 is a rectangular steel gage block measuring 0.101 inches, manufactured to Grade 0 accuracy. Gage blocks are precision ground and lapped reference standards used to verify, calibrate, and set measuring instruments such as micrometers, calipers, and comparators. This block meets ASME standards and includes a Certificate of Inspection, confirming dimensional accuracy at the time of manufacture. Grade 0 represents a high level of precision suitable for inspection room and laboratory applications. Machinists, metrologists, and quality control technicians use gage blocks as a traceable length reference in dimensional measurement workflows.

This 0.101-inch block is intended for use in precision measurement environments including machine shops, inspection labs, and toolrooms. It functions as a standalone reference block or as part of a gage block set when wringing multiple blocks together to achieve a target dimension. Grade 0 blocks are appropriate for applications requiring tighter dimensional tolerances than Grade AS-1 or Grade K blocks, making them a standard choice for calibration and inspection use cases in both light manufacturing and precision machining environments.

Key Features

• Grade 0 accuracy per ASME standards, suitable for inspection and calibration use
• Rectangular steel construction provides durability and stable thermal properties
• 0.101-inch nominal size for precise dimensional reference
• Includes Certificate of Inspection for traceability documentation
• Compatible with wringing techniques for building compound dimensions

Compatibility

Designed as an OEM-style individual gage block for use in standard rectangular steel gage block sets and general-purpose dimensional measurement applications conforming to ASME specifications.

Installation Notes

Gage blocks should be handled by metrology technicians or quality control personnel following proper wringing and storage procedures. Clean block surfaces with an appropriate gage block cleaning solution before and after use to prevent corrosion and contamination. Store blocks in their protective case when not in use to avoid surface damage. Do not drop or contact blocks against hard surfaces, as edge damage will compromise measurement accuracy.
