Mitutoyo 611159-531 Steel Gage Block 0.119 in Grade 0

Product Description

The MITUTOYO 611159-531 is a rectangular steel gage block measuring 0.119 inches, manufactured to Grade 0 accuracy. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, verify dimensional tolerances, and set up inspection fixtures. This block meets ASME standards and ships with a Certificate of Inspection, making it suitable for use in quality control labs, tool rooms, and metrology departments. A licensed metrologist, quality technician, or precision machinist typically puts this block into service as part of a calibrated reference set.

This gage block is suited for dimensional verification tasks in manufacturing and inspection environments where Grade 0 accuracy is required. It functions as a direct reference standard for calibrating calipers, micrometers, comparators, and height gages. The 0.119-inch nominal size fills a specific increment in a gage block set and is commonly used in both stack builds and stand-alone gauge setup applications in machine shops, production floors, and metrology labs.

Key Features

• Grade 0 accuracy per ASME standards for high-precision dimensional reference work
• Rectangular steel construction provides durability and wear resistance under repeated use
• 0.119-inch nominal length for precise increment coverage in gage block stacks
• Includes Certificate of Inspection for documented traceability
• Complies with ASME gage block standards

Compatibility

Designed as an OEM-style precision reference standard compatible with standard rectangular gage block accessories, holders, and wringing fixtures used in ASME-compliant metrology setups.

Installation Notes

Gage blocks are handled and stored by metrology technicians or quality control personnel, not installed in the traditional sense. Always clean contact surfaces with lint-free cloths and appropriate solvents before wringing blocks together. Store blocks in their protective case away from humidity and temperature extremes to maintain calibration integrity. Periodic recalibration against a national standard is recommended to maintain traceable accuracy.
