Mitutoyo 611167-531 Steel Gage Block 0.127 in Grade 0

Product Description

The MITUTOYO 611167-531 is a rectangular steel gage block measuring 0.127 inches, manufactured to Grade 0 accuracy and supplied with a Certificate of Inspection. Gage blocks are precision reference standards used to calibrate measuring instruments, verify part dimensions, and set comparators to a known dimension. This block is machined from steel and meets ASME standards for dimensional accuracy. Grade 0 represents a high level of precision suitable for toolroom and inspection applications. Each unit ships individually and includes documentation confirming dimensional conformance at the time of manufacture.

This gage block is used in calibration labs, quality control departments, and toolroom environments where traceable dimensional reference is required. Typical applications include setting dial indicators, height gages, and optical comparators. It is appropriate for both production floor inspection and bench-level metrology work in industrial and manufacturing settings. The included Certificate of Inspection supports traceability requirements common in ISO and AS9100-regulated environments.

Key Features

• Grade 0 accuracy per ASME standards for high-precision dimensional reference
• Nominal size of 0.127 inches machined to tight tolerance
• Steel construction provides durability and wear resistance in regular use
• Includes Certificate of Inspection for traceability documentation
• Rectangular form compatible with standard gage block accessories and holders

Compatibility

Designed as an OEM-style precision reference standard compatible with standard rectangular gage block accessories, holders, and wringing sets used in toolroom and metrology applications.

Installation Notes

Gage blocks are handled and set up by metrology technicians, quality control inspectors, or toolroom machinists. Before use, clean all mating surfaces thoroughly to remove oils, debris, and burrs that could affect dimensional accuracy. Wring blocks together with gentle sliding pressure rather than forcing them to avoid surface damage. Store in the supplied case away from temperature extremes to maintain dimensional stability and prevent corrosion.
