Mitutoyo 611128-531 Steel Gage Block 0.1008 in Grade 0

Product Description

The MITUTOYO 611128-531 is a rectangular steel gage block with a nominal length of 0.1008 inches and a Grade 0 accuracy rating. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances on the shop floor or in a metrology lab. Grade 0 represents a high level of dimensional accuracy, making this block suitable for calibration work and precision inspection tasks. A Certificate of Inspection is included, confirming that the block meets the stated dimensional tolerances as verified at the time of manufacture.

This gage block is used in tool rooms, calibration labs, and production environments where reliable dimensional reference is required. It is appropriate for setting dial indicators, height gages, and optical comparators, as well as for direct comparison measurement. Machinists, metrologists, and quality control technicians working to ASME standards will find this block compatible with standard wringing sets and individual reference applications. Its steel construction provides the durability needed for regular shop use.

Key Features

• Grade 0 accuracy rating meets ASME standard requirements for precision reference work
• Nominal length of 0.1008 inches for fine incremental measurement setups
• Steel construction for durability and resistance to wear during routine handling
• Includes Certificate of Inspection for traceability documentation
• Individual block format suitable for supplementing existing gage block sets

Compatibility

Designed as an individual replacement or supplemental reference block compatible with standard rectangular steel gage block sets conforming to ASME specifications.

Installation Notes

Gage blocks are handled and wrung together by metrology technicians or machinists — no mechanical installation is required. Keep block surfaces clean and free of debris before wringing to prevent scratching. Store blocks in their protective case when not in use to prevent corrosion and surface damage. Follow your facility calibration procedures and applicable ASME standards when using gage blocks for formal calibration activities.
