Mitutoyo 611152-531 Steel Gage Block 0.112 in Grade 0

Product Description

The MITUTOYO 611152-531 is a rectangular steel gage block measuring 0.112 inches in overall length, manufactured to Grade 0 accuracy. Gage blocks are precision reference standards used to calibrate measuring instruments, set up comparators, and verify dimensional tolerances on machined parts. This block ships with a Certificate of Inspection, confirming it meets the stated accuracy grade at the time of manufacture. Grade 0 blocks are suited for toolroom and inspection applications where close dimensional control is required. Machinists, quality technicians, and metrology lab personnel are the primary users.

This gage block is used in toolrooms, inspection departments, and calibration labs where dimensional reference standards are needed. It serves as a setting standard for micrometers, dial indicators, height gages, and similar instruments. The 0.112-inch size makes it a useful component in combination sets for building up specific stack dimensions. Applications span general manufacturing, precision machining, and quality control work in both light industrial and production environments.

Key Features

• Grade 0 accuracy per ASME standards, suitable for toolroom and inspection use
• Rectangular steel construction for durability and stable dimensional performance
• 0.112-inch nominal size for use in gage block stacks or as a standalone reference
• Includes Certificate of Inspection documenting conformance at manufacture
• Meets ASME standards for gage block accuracy and geometry

Compatibility

Designed as a standard rectangular steel gage block compatible with conventional gage block sets and accessories used in toolroom and metrology applications.

Installation Notes

Gage blocks are handled and stored by metrology technicians and quality control personnel, not installed in the traditional sense. Clean contact surfaces thoroughly before wringing blocks together or placing them in a comparator fixture to prevent contamination that could affect accuracy. Store in the provided case away from humidity and temperature extremes to maintain dimensional stability. Calibration intervals should follow the applicable ASME or facility quality standards.
