Mitutoyo 611156-531 Steel Gage Block 0.116 in Grade 0

Product Description

The MITUTOYO 611156-531 is a rectangular steel gage block with a nominal length of 0.116 inches and an accuracy grade of Grade 0. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set up comparators, and verify dimensional tolerances on the shop floor or in a metrology lab. This block is manufactured from steel and ships with a Certificate of Inspection. Grade 0 represents a high level of dimensional accuracy, making it appropriate for lab environments and precision inspection work where tight tolerance verification is required.

This gage block is used in quality control labs, tool rooms, and production environments where traceable dimensional standards are required. Typical applications include calibrating micrometers, height gages, and surface plates, as well as establishing reference dimensions for machining setups. It is suitable for use by metrology technicians, machinist inspectors, and quality engineers working to ASME standards.

Key Features

• Grade 0 accuracy per ASME standards for high-precision metrology applications
• Nominal length of 0.116 inches in rectangular form factor
• Steel construction for durability and dimensional stability
• Includes Certificate of Inspection for traceability documentation
• Single-block quantity suitable for selective set building or individual replacement

Compatibility

Designed as an individual rectangular steel gage block conforming to ASME standards, suitable for use as a standalone reference standard or as a component within a gage block set in precision metrology and inspection applications.

Installation Notes

Gage blocks are handled by metrology technicians and quality inspection personnel, not typically installed in a mechanical assembly. Store blocks in a clean, dry environment away from temperature extremes to preserve dimensional stability. Always clean contact surfaces thoroughly before wringing blocks together, and avoid dropping or sliding blocks across hard surfaces to prevent damage to the lapped faces. Follow ASME B89.1.9 guidelines for proper care, handling, and calibration intervals.
